So, myself and my partner are trying to conceive, I don't wanna go on any medication but we have been having unprotected sex for well over a year now and still no joy. I finished my on a thurs which was 10 days ago and had sex in the Monday, 5 days later( which would make it last night)I got that sting/pinch feeling in my lower left side like I was ovulating and today I have white discharge. Iv read that sperm can last up to 10 days? Is this true? Could I be pregnant?
