My last mp was on sept 4.had int on oct 8, protected and no fail. Missed period the following month becoz I was taking sevista 30 for breast fibroadenoma and the tablet delays period as suggested by my gyenic. I got cramps after stopping the medication but no period so prescribed meprate and got period after 8 days of stopping meprate i.e. On 8th of nov. I did transabdominal ultrasound as per my doc's advice on 21st nov (6 weeks after int, technically if preg it would be 8 weeks) and everything was normal, uterus size was normal but got multiple follicles on both ovaries. Again this month I got cramps for almost 10 days and got my period on 19th dec and my due date was 8th dec. This time I had very heavy flow with heavy clots for almost 2 days and 3rd day was normal flow and spotting on 4th, 6th day. I usually get period 8-10 days later on my regular cycle days and this period was much similar to my previous cycles. On 19th I again did ultrasound transabdominal since I was not getting my period till then, I had normal uterus, size-7.1�3.6�4.2 and endoecho-10.8 mm. Basically this is 10 weeks after sex and almost if considered 12 weeks if i'm pregnant. Is it possible to be pregnant in my case and is it possible that transabdominal ultrasound not able to detect pregnancy even after 10 weeks of having sex or at 12 weeks of pregnancy or is it confirmed that i'm not pregnant? Please suggest. Should I conduct some other tests where I could be 100% confirmed that pregnancy is not there. No sexual contact post 8th oct. I am in a very bad mental condition these days for this scare, please help.
