Hmmm... symptoms??

Clarissa • My name is Clarissa. I`m 21 years old. I have an amazing SO.
So the last week or so I've been having real annoying lower back pain, fatigued, and sore breasts. Today, I was headed to a friend's appointment and out of no where I had to pull over and throw up, all water, and just a lil bit ago immediately after I ate it happened again... what do you think??
