(Phineas's POV)

(The next day)

I awoke groggy, but I had finally become accustomed to being in Isabella's body; that I wasn't surprised when I saw her in the mirror. After getting dressed and combing my hair so that it finally stayed down, I went downstairs to get breakfast; before going to my house to see what was happening. When I got downstairs I noticed Isabella's mom had finished making pancakes and had set them on the table; she was now washing the dishes.

"Good morning Mom." I said as I took a seat. "Thanks for the pancakes." I took a serving and began pouring the syrup. I'm actually referring to Mrs. Garcia-Shapiro as 'Mom' … can't say I haven't been hoping to do that at various points in my life recently.

"Good morning Isa." She greeted as she took a seat across from me. "I see that you're feeling as energetic as ever." I smiled and continued eating my pancakes. "That's good to know. Do you plan on going to Phineas's house again today?"

I swallowed before answering. "I didn't go yesterday or the day before, but yes, yes I do." I quickly took another fork full and scooped them into my mouth. I figure by now I've gotten accustomed enough to being Isabella that I shouldn't have to worry, too much, about any more surprises.

"I heard about what happened at the Fireside Girls' lodge two days ago Isa." She said as she smiled at me, yet clearly emanating some form of ominous tone. "I think it's time we had that talk again."

Of course. I thought. I just had to think it.

"Now, I know I've told you this before, but you're a growing girl. While I'm not prohibiting you from getting a boyfriend, I want you to know that you have to be careful."

I quickly finished my remaining pancakes and tried to find a way out of the conversation; as soon as possible. "I know Mom, but Phineas isn't my boyfriend, we're just friends."

"I know." She said as she reached across the table and patted me on the head. "But one day you two may be very close; and I just want you to know that you two should take it slow."

"He's not my boyfriend Mom." I reiterated as nicely as I could. "And I don't think he will be any time soon."

"You say that now." She said with a smile. "But sooner than you think, the two of you will be a couple. I want you to make sure that he doesn't push you further than what you're ready for."

"Mom!" I hollered in embarrassment.

"And even when you are ready you should use protection, you're the one who has to give birth after all."

"Mom, please, I don't plan on going too far, even if I was going to start dating Phineas."

"I know, I know." She said calmly. "But it will happen faster than you think. It'll be late one night, I'll be out of the house or maybe Phineas's parents and family; you two will go to one of your rooms with promises to just talk. But as the night roles on, emotions grow stronger and before you know it you're-"

"I get the picture mom." I interrupted.

"It's going to be the sheer amount of these talks that breaks through at the last minute and snaps you out of it."

"Thank you." I said as I got up. "And now I think I'm too embarrassed to even talk to Phineas right now."

"Maybe I should talk to both of you at the same time then."

"NO!" I hollered as I stepped back in fear. "That would strain our friendship."

"All right." She said with a smile. "Go play, but remember what I said."

"Okay Mom." I said as I rushed out the door. "Man, that was … uncomfortable." I shivered. "And why did she think that Isabella and I would get together eventually? It's not like Isabella has romantic feelings for me or anything … I guess it's just an example of how it could happen extremely fast." I shivered again and continued walking. "But it's not like Isabella would ever want to go out with me or anything."

I reached the gate to my back yard and took a deep breath, then opened the gate. "What cha' doin'?" I asked in the cutest voice I could muster.

"Ah, Phineas." Isabella said from where she was sitting underneath our tree. "I see you finally managed to get your hair under control."

"It was tricky, but I finally mastered it." I said as I walked into the backyard. I looked around expecting to see Ferb either sitting next to Isabella or somewhere in the backyard; but he was nowhere to be found. "So, where's Ferb?" I asked.

"He said he had plans with someone, he never mentioned who." Isabella answered. "And to be honest, I'm glad it's just the two of us."

"Yeah, I guess we haven't been able to spend much time as just friends." I said as I scratched my ear. "And the whole, we're in each other's body thing."

"About that." Isabella began as I walked over and took a seat next to her. "I … kinda have to apologize about something I said."

I looked at her curiously. "What?"

She sighed and looked away. "The other day … I said that boys had it easier than girls … I would like to retract that statement."

"So your saying that boys have it just as bad as girls do?" I asked as I looked at her sheepishly.

"No." She retorted. "I'm saying that when it comes to everyday life, it is unknown what is more difficult."

"I can live with that." I said with a smile that quickly turned into a look of confusion. "What do you mean when it comes to everyday life?"

"Well girls … from what I've heard, have a really hard time during pregnancy; which boys don't have to deal with so-"

"I beg your pardon!" I spat. "I'll have you know that a real man sticks by his girl when he gets her pregnant and has to deal with their violent mood swings and needs at all times."

"Well dealing with a pregnant woman isn't as bad as the act of giving birth." She said as she looked at me from the side.

"Well you know what?" I asked as I put my hands on my hips. I opened my mouth to comment but quickly stopped myself. "No, I'm not going to compare ANYTHING with childbirth." I sat back down and looked over at her. "So, how was your day yesterday?"

"Well, I injured myself a few times, got laughed at, … oh, and I got nailed right between the legs with a ball."

I paused for a moment before bursting into laughter. "So that's why you no longer believe that girls have it harder than boys."

"Well yeah, and what's with all the sweat?" She asked. "By the time I got home I was drowning in sweat; I felt like I needed to take two showers."

I laughed a bit before remembering something that happened recently. "Oh, before I forget, your mom had a little talk with me about … well … us."

She suddenly looked like she had seen a ghost and looked over to me, slowly. "What … did she say exactly?" Isabella asked nervously.

"Well …" I began. "She thinks that just because we kissed a few days ago that we will eventually become a couple, and have children before we're ready."

She continued staring at me for a few moments before bursting into laughter. "Oh, … yeah, she does that a lot … For some reason, she thinks that the two of us are going to become a couple this summer."

"Well that's ridiculous." I said as I scratched my ear as my heart rate began to pick up. Mrs. Garcia-Shapiro isn't the only one who want's that to happen … does she want that to happen, or does she only think it's going to happen?

"I know right?" Isabella said as she played with some of her hair. "I mean … maybe we'll get together at some point in our lives, I mean nothing's impossible, but this summer, really?"

I froze. "Wait … you really think that … we might … end up together?"

She looked at me almost nervously. "Well … who's to say … I mean … you yourself said that nothing's impossible even if it might be farfetched but … this summer? Really?"

"Yeah." I said nervously. "Farfetched." I began to feel a little uncomfortable and began shifting around.

"And even if we were to get together this summer, would we really be doing that?" I laughed, it came out sounding forced.

"Yeah." I said again as an uncomfortable sensation began to get stronger and almost felt like a cramp.

"I know, isn't that insane?" She asked with an almost fake laugh.

"Yeah." I said as I began rubbing my legs together. The cramps were now very distinct and I tried placing my hands on my abdomen to try to get them to stop.

Isabella looked over at me obviously concerned about my strange position. "Hey, are you feeling all right?"

"I'm getting this cramp." I said as I squirmed a bit more. "It's really starting to get annoying."

Isabella looked at me for a moment. "Oh … um …" She smiled weakly and looked to the side. "Yeah, um … Phineas, don't freak out but … you're having your period."

I felt a cold sensation come over me. "WHAT!?" I hollered. "Oh my god, this can't be happening."

"Now don't worry Phineas." Isabella said as she patted me on the back. "All we need is to … um … we need to get you to the bathroom."

(Phineas's POV)

(A short time later)

I was sitting down in our downstairs bathroom, waiting for Isabella to return with a new pair of underwear. "I'm back." I heard from the other side of the door. "How are you faring?"

"This feels weird." I responded. "Do I really have to wear a tampon?"

"Do you want to drip everywhere?" Isabella asked as she reached in and handed me another pair of underwear. "I'm just glad that my mom decided to leave shortly after you did."

"How long am I going to have these cramps?"

"The actual period lasts for about a week but the cramps should go away in a few days."

"A few days?!" I hollered. "You mean I have to deal with this for a few days?"

"Oh, come on!" She retorted. "It's not even half as bad as a boy getting hit between the legs!"

"At least that only lasts for an hour." I said as I walked out of the bathroom.

"You can deal with a few days of cramps Phineas." She said as she crossed her arms.

"Fine!" I shouted in defeat. "I'm just glad that this is the worst possible thing that could happen to me while I'm like this."

I don't have much for this authors note so I will see you all another time.
