Hello Doctor, I just want to know if I am pregnant or not. My last period day was from 6-9th November and I had unprotected sex on Nov.29 according to my calculations my next period should have been Dec.4 and I haven't seen my period. I'm 26. Also not sure if my boyfriend mistakenly cum inside me. So I'm just going to say assuming? I also do not understand the ovulation thing. Could you save me from this worry.
