As I said I use birth control and condoms also since my last period we have only had sex once so I'm 100% nothing went wrong (also it was only 10 days ago). Around the time I should have been ovulating I had Uni exams, money stress etc. but I dont know if this would delay it so much. Normally my period is like clockwork so I'm quite concerned. Had discharge that was a very light brown then one that was white/yellow today. I've been having cramps for about 8 days now and originally I thought they were particularly bad period pains. Also the past two times we have had sex it has been painful for him to enter but fine after ( I dont know if this is relevant).
