I'm not sure if i'm pregnant or not. I had sex 4 da first time in my life on the 28th of june this year. After that me and my boyfriend have been having sex when the opportunity comes to us.Sometimes we have protected sex. Other times we start off without protection but when he's gonna cum he gets out and cums sumwhere else. Well, onetime not to long ago like 2-3 weeks ago we did it like dat. We were at his house and we did a ''quickie'' . When he was gonna cum he pulled his penis out and his sister walked in. So, he cummed all over my private area and I pulled my pants up without cleaning myself. We had no time to do that. So we've been having sex unprotected most of the time but when he cums he does it outside ''supposly''. After the occurance I started to feel cramp -like pains in the middle of my abdomen. Which never happened before. About a week later I got my period a day late and only lasted 3 days when it was supposed to leave the 4th day starting the 5th day. It left and I started to feel those pains once again inthe same area. Whenever I layed face down my abdomen hurted or felt uncomfortable.Sometimes when I lay on my left side my left side of my abdomen hurts and feels weird.In my upper leftside of my stomach I sometimes feel a little pain but not common like when I lay down or on my left side. My nipples were pink since I cant remember.About 4-5 days I noticed that my nipples are getting darker and they hurt. Also my left breast and sometimes right breast hurt. But I dont know why.My breast also feel softer and more smushy if I could use dat word than before. So i'm confused if I am or not. Can someone please help me or tell me their experiece. That would do me good and bring me comfort because if i'm not then im happy I dont want to tell my mom or my boyfriends mom. So please help me e- mail me or reply but please sum 1 help me i'm desperate.
