My period is four days late. pull out method ten mins before ejaculation and pre ejaculation was wiped constantly. what do you think?

Stop !: If you don't want to get pregnant stop this method immediately. If you have missed a period check a home pregnancy test. If negative use condoms or birth control pills to avoid pregnancy. Get an evaluation by your physician, get to your local health department, use condoms or don't have sex if you don't want to run the risk. The method you are using will likely result in pregnancy. Good luck.
