As previously stated Pre ejaculate does contain some sperm. Unprotected sex can always lead to pregnancy. Use protection. Invest in a pregnancy test. Put your mind at ease.
Good luck.
you wouldnt not know if you pre ejaculated inside of her. And know that anytime you have unprotected sex you can very much get someone pregnant. so always use a condom. your going to have to wait now.
pre ejaculate. you produce it during the entire time. from start to finish and normally a man can't feel it but it does contain sperm. so she could be pregnant. ask her to take an hpt if her period is late.
