I'm 16 and I figured I was pregnant because I usually use birthcontrol but the guy I've been with came inside of me multiple times right after my period so I stopped taking birthcontrol because I didn't want to hurt the baby if their was one. I've been very sick to my stomach and have abdomen pains. I've been exhausted too but that might be from work. I'm bleeding very lightly but usually the first day of my period is extremely heavy... Could I still be pregnant??? I've also been off the pill for about 5 days...
