So I had protected sex with my boyfriend last Monday and the condom broke , but he wasn’t near cumming . I’m 16 and then we had intercourse 2 days after with condom. We also had intercourse yesterday Monday June 11 .My period was supposed to come on Sunday but it’s 2days late and I have tender breast ? And back pain . I also have pain under my belly button. Iv been stressed out since the first time we had intercourse and he is 100% sure he didn’t ejaculate in me . Iv been seeing white dry discharge on my underwear I need help to understand what’s going on.
