So I'm 15... Missed my period, I usually get it around the 27, latest the 1st. I dont know if this is important but my hormones went crazy the week I was supposed to have it, as it does when I do have my period. I got really sick the past week. Threw up the other night and felt better this morning... Kinda. I've been having major headaches.. Unbearable headaches. And pain like crazy in my stomach and vaginal pain like crazy. I dont know what to do or think. I took a pregnancy test just in case even tho I've lost 13 pounds since the last time I had sex which was like a month and a half ago. Help?:/ my mom was sick and pukey with the headache and is over it now. Very rarely do I get sick.
