Q: How long before I ovulate will my mucus become stretchy?


A: Spinnbarkeit, the ability of the mucus to stretch like egg white (EW or EWCM = Egg-White Cervical Mucus) usually starts several days before ovulation and ends within one to two days after ovulation (see graph here). However, many women report it happens longer, or shorter, before ovulation, and some women have no egg-white fluid at all despite good and regular ovulation.
