I'm on the depo shot and I'm supposed to get it again tomorrow. I began taking the pill 3 days ago, but had unprotected sex before that. Is there a possibility I'm pregnant?? I'm just making sure because I've been very hungry lately and very tired. Also, I was bleeding for about 2 weeks before I started the pills then it stopped. Maybe it's just my hormones. Anybody with the same problems?? Lol
