Hi doctor i am 27 year woman trying to get pregnant. This month we did unprotected sex during ovalution window and after few days of that i felt that intercourse is very uncomfortable for me, it hurts suring sex. Also i dont have any symptoms of periods. I am taking folic acid tablets these days, can these tablets are affecting my body or it may be a sign of pregnancy? I have not any pregnancy symtom except too much gas and bloating? I did pregnancy test before 3 days before expected period but its negative. Please help me
