My boyfriend and I had sex without any form of protection. We did it once and he didn't cum, but a few minutes later we had sex again and he did cum. When he did he pulled out but I thought I felt a warm liquid go on my vagina.(note not in my vagina but in the wet area towards the opening of the hole of the vagina) I haven't taken any morning after pills and after we finished having sex a couple hours later I had extremely sore breasts and I felt crampy.(could this maybe be ovulation?) My period is very irregular (like a month off then 2-3 months on my period) so I don't know if I should test. No rude/negative comments please!! I desperately need advice
