So I'm 19 years old soon to be 20 and my boyfriend and I have been dating for almost a year now (next week will be our one year!). After a couple of months of dating we started to have sex without condoms since I had birth control. Until recently I stopped taking my birth control since I couldn't get a refill. Since I stopped my body had 3 periods in one month (I'm assuming it was just my body trying to regulate itself with my own hormones). I finally received my birth control however I have to wait until my next period to start taking them. Its been a month since my last period and I'm still waiting. I'm a little nervous now because my nipples have been sooooo tender that I only allow my boyfriend to put his mouth over them, nothing else and because we've been having unprotected sex (he pulls out though). I wasn't sure if my nipples are sore due to my bra, or if my period is finally coming, or I may be pregnant. If somebody could help me out I would appreciate it!
