I recently started having sex again after being abstanant for over two years. My SO and I have been having sex often and using condoms when he finishes but not when we first start. I am now 3 days late I have taken a few pregnancy tests and they have all come back negative. Do your cycles change when you're sexually active? Any of you ladies gone threw this too? I'm probably going to wait till the end of this week before intake another pregnancy test. Thanks in advise ladies!
