Hi everyone So I'm 18 years old and have been on the pill since I was 15. I haven't been taking it for about 4 months as it stuffed up and I needed to start it over again. Anyway I've been having unprotected sex. And now my period is 39 days late. I noticed yesterday my breasts are sore and my nipple are very tender and painful to touch. (Getting worse as it now hurts to have a bra touching them) I've taken 5 pregnancy tests over the past 2 or 3 weeks and all negative. Should I just stop being stubborn and go to the doctor?
