My last periods were on 23rd July and ended on 28th. I had unprotected intercourse with my partner on 30th of July, however, he did not ejaculate inside me as we are not trying to conceive. My periods are generally irregular but I was expecting them to arrive between 23rd August to 3rd September. It's almost a month I have missed them.
Between 23rd August to 3rd September, I had acme (which is normal when periods is due). But I was also stressed whether I am pregnant (which might have delayed my periods).
I took home pregnancy tests since 3rd of September on every alternate day and all 5 were negative. I finally took Beta HCG test on 11th of September and my HCG count was less than 2. I am having no sign of pregnancy, what could be the reason of my missed periods?
