So told one of my good friends that I’m trying to have a baby and she told me only the have sex on 13th and the 15th because the sperm stays in your body for seven days and then I have some friends are like have sex everyday but the sperm gets thin and with the 2 day I can get pregnant so let’s see what you guys think ??
You should get a period tracker app like ovia, which tells you when you are most fertile. and when you're in your fertile days window / week, every 2 days should be good.
