“Fertile mucus usually occurs two to three days before ovulation, but it can occur anytime when there is very high estrogen compared to progesterone. It can happen earlier in the cycle if you have higher than normal estrogen. It can even happen after ovulation if you do not have enough progesterone. It is therefore possible to see fertile mucus more than once in a cycle.”
