My partner and I are ttc, and have been for 3 months without luck so far. We usually only have sex 1-3 times a week (usually on the weekends.) We have sex on days that I think I am ovulating and very fertile. Last time, we had sex on one of my very fertile days just a day or 2 before ovulation. Is this enough sex? Should we have sex more often or is this enough if it is around my fertile days?
