Hi, I am 25 years and I am engaged. I had sex with my fiancee unprotected (12 days before due menses date) and he did not cum inside me. 2 weeks later, I was still not getting my menses and I did a pregnancy test , it revealed negative. Now it has been 3 weeks, still not getting it. Long ago, some 7 years back, I had irregular menses because I was anaemia patient but had visited a doc. After that, did not had that problem again. Also would like to mention that when I had sex with my fiancee the 5 last time, I took pills Norlevo to avoid getting pregnant. Does this have a negative effect on my menses now? Thanks to advise ASAP.
