Had sex with condom. but went in a couple times without it. peed an hour before sex. could there be sperm in precum? enough to impregnate?

Chance of pregnancy: Even with a condom, there is always a small risk of pregnancy. Engaging in sexual activity/intercourse WITHOUT the condom, even if you put one on eventually, greatly increases that risk. Yes, there can be sperm in pre-ejaculate and NO you can't always control it. To reduce risk of pregnancy always put on the condom BEFORE engaging in sexual activity.
