I had unprotected sex on 16 june. Then I had done home pregnancy test on 10 july ,22 july& 11 september that all were negative, I was tensed and had done beta hcg blood test on 4 aug and the value was 0.584miu/ml. Then I take primolut n tablet (from 11 sept) for 10 days 2 times in a day. After that I had protected sex using condom on 14 september then I got periods on 29 sept after 2 june. My periods are irregular so I got my periods after 1-2 month of gap and I used to face heavy bleeding and generally lasts for 10-15 days. But in september the bleeding lasted for only 2 days (till 1 oct) and 3 days spotting.(4oct. Then I had protected sex using condom on 3rd november. & I didn't get periods after 29 sept till today. My tummy looking big I don't know it is because of my weight or because of pregnancy. I feel pain in lower abdomen (chamak ati hai). White discharge is also increased from june. Headache also. So am I pregnant or not? Or is there any possibility that I might be pregnant? And after having protection during sex (condom) still there is any chance that i'll be pregnant? Please tell me because of this I am very confused and worried I can't even eat or sleep properly because of this tension? Please help me and confirm that am I 100% not pregnant or there is still any chance of pregnancy?
