So, I'm 15 years old, and uv been on my depo for 2 years now. If been with my boyfriend a eat now, and were having unprotected sex. When we dining get really bad cramps and sometimes I throw up. I feel nauseous everytime I smoke ciggs also. I usualu don't use the bathroom much, but when I do it's really runny. My bigeat issue is that conatantly exhausted, and have no energy to do the sImpelest task( like cleaning or something). I'm worried that there us something wrong. And I'm worried that it's not because I'm pregnant. What's wrong with me?!
