Following menstruation there will often be a number of days when you feel dry and don't see any discharge. This is called the Basic Infertile Pattern (BIP). We know from the work of scientists that the hormone levels are low at this time and the cervix is blocked by a thick plug of mucus which prevents sperm entering the uterus. This means that you're infertile at this time.
