I've been on birth control for 4 years and last time I had sex he pulled out way before he was about to cum. He came on my breasts and some dripped down to my belly button but I cleaned it off. But now I'm supposed to have my period and it's not here all I have is pink/brown spotting and everything I read says early pregnancy. My bf and my best friend are both telling me I'm not pregnant and that I'm stressing myself out and that's why my period isn't here, I have cramps like my period is here and all the other signs of period I'm just not bleeding. Can someone please tell me if I'm okay and that I'm just stressing myself out and that's why it's not here??
