Leonard and Penny were getting ready to head out. They had an appointment with the doctor today, to check up on the baby. They want to see the baby, to make sure that it's ok.

When they got there they were placed on the doctor's bed, he said if they don't find the baby not to panic, as it is so young, it will be so low down. But when they started the ultrasound, the baby was higher up than expected, so she was further along than they thought. When they looked harder they saw something unexpected, something pretty common but still a surprise for many families.

"Well number one, you are twelve plus weeks, and number two, is that this baby is not alone!"

Penny looked in confusion, what was he on about.

"From what it looks like, this is a multiple pregnancy."

"I'm sorry, what?"

Leonard had his face scrunched in horror as the doctor moved the monitor. They saw two embryo's.

"They are monochorionic twins, meaning they share a placenta. they are identical twins, coming from one egg."

"So we either have two boys, or two girls" Penny asked.

"Yes, now we're going to do a few tests, to find out how far along you exactly are so we can get a accurate due date."

They did a few tests and they came back saying that the babies were about fourteen weeks along.

"Due to you being further along, we can tell what the gender of the babies are, of course it is up to you, and you will need to come back in a few weeks to make sure it is that"

Leonard looked at Penny, they weren't quite ready to know,

"No, I'll think we'll wait a few weeks"

"Sure"

The doctor left the room, giving them some privacy. They got packed up and left the room.

"So we've got twins, we weren't expecting that!"

"No, we really weren't!"

When they got home they called everyone they knew, telling them that they were having twins. Everyone was over the moon, they couldn't be more happy for Leonard and Penny, and wished them the best that they needed on their journey from just being a couple, to being a family of four.
