I and my girlfriend had sex on 23rd jan using protection. Yesterday she felt 100�C body temperature. She is having a viral fever now and she was going to have her periods on 26th jan but still not got it (29th jan). She is having gastric problem today. She is not feeling anything like Vomiting, Fatigue, or Back shoulder paining. Her breast is looking a little bit bigger today. She is having no problem in urination. No mood swing or any other syntomps .except period missing and fever. We are doubting that the condom was leaking and maybe the fertilization has started and she is going to be pregnant. Please doctor suggest or give me advice or any syntmps that she is pregnant? Is getting period miss for 3-4 days and fever .syntomps of early stage of pregnancy?
