I had sex with my now ex boyfriend last Monday and we used a condom, he said he didn't cum, and the condom didn't split or anything...but my nipples are very like hard, and they're perky. And I'm not craving anything, I eat normally, I just been a little tummy sick. I don't throw up but I feel slightly sick often whenever I think about having a baby at 15 YEARS OLD!!!!! I don't have my period yet, I'm supposed to get it sometime this week actually. I just need to know if I'm stressing out too much because one day we have sex FOR THE FIRST TIME and two days later, he's "not ready for a relationship". Please Help!
