Bulma awoke with a minor head ache and her chest hurting once more. Gohan was over her, which she freaked out over.
"Oh my god! When did you get here?" Bulma asked, eyes wide with shock.
"A couple of minutes ago..." Gohan replied, focusing on her temperature. He gently shoved a clear glass thermometer in her mouth. A minute later, he got it out and "tsk"ed.
"You have a high fever mrs. Briefs. You need to rest. But it only appears to be a cold. It'll pass by. Bye Bulma! Get well soon!" And as soon as he said it, he was out of the plush room and going down the hallway out to go home.
Bulma really wanted some Tylenol. It was everyone's best friend, seeing as it helped with several things. She half hoped it would cure the ache in her chest. Then a series of coughs racked her body. When she had recovered from her coughing fit, she noticed a bottle of water next to her on the end table next to her head. She grabbed the plastic bottle in her hand and unscrewed the lid. She took a long drink of water and she felt a bit better.

Bulma tried to relax more onto her pillow and go to sleep once more. But the ache in her chest forbid it. She hadn't told about the ache, so she just presumed it was just part of a cold. Also, strangely enough, she hadn't eaten anything at all today but she had no appetite. She didn't know how to solve that either.
As Bulma started coughing again, she heard light footsteps in the hallway; Vegeta had left the door open so Bulma wouldn't feel so confined as she recovered.
Trunks came into the room with a bundle behind his back.
"Mom?" Trunks asked, "are you bored?" Bulma thought about it for a moment. Yeah... She actually kinda was.
"A little. Why?"
"Well I thought you would! So I went and grabbed a bunch of your romance novels for you." Trunks handed her four romance novels by her favorite author, and smiled.
"Thanks Trunksy." She leaned forward and kissed the top of his head. Trunks grumbled at the kiss but Bulma knew he had taken a liking to them.
Bulma didn't mind trunks staying, but Bulma never knew when she had woken up at such a late hour. When she checked a clock, it read 9:34 PM. Bulma looked at trunks who was yawning silently.
"Time for bed." Bulma smiled and kissed him goodnight while still lying down. Trunks wished her goodnight and ventured back to his room. Bulma still hadn't felt hungry in the last few hours. Bulma put it aside as her just feeling full from something yesterday. Bulma started to feel worse. It began to feel hotter, and her lungs started to hurt this time. She tried coughing to clear her throat but it hadn't worked. She coughed into a tissue and what she saw on the tissue after she had coughed shocked her.

Bulma had coughed up blood.
