I am 32 years old. I had unprotected sex on 15 Oct and my partner did not ejaculate inside. But I took an ipill on 16 Oct to be safe. I then got my periods on 6th Nov but they were very light and only lasted for about 2 days. After that my next period was due on 3 Dec, but I have not got it till now. 4 HPTs were negative, I also got a beta HCG blood test done. first count was 0.04 and second time after one week it was 0.41. I took meprate for 5 days and no periods, doctor has now given me deviry. What do i do
