Hi,
I read this on some other forum:
Take Evening Primrose Oil (High Strength) from first day of period for 14 days, then stop at ovulation and DONT take for another 14 days or until your period comes again. EPO can cause your period to start, that is why you only take it up until ovulation, not after. Its a stop and start supplement not to be taken permanently. If pregnant, dont take. But keep using this procedure until you do become pregnant! Evening Primrose Oil is a herb that is often used specifically to help increase cervical mucus. Evening primrose oil is an essential fatty acid that is also an anti-inflammatory. Evening primrose oil will not only help to increase cervical mucus, it can also help to increase the quality and effectiveness of cervical mucus, and produce more egg-white cervical mucus. GQCM can help the sperm reach the egg easier. It can make the uterus a less 'hostile' place. Taken over time, it can help reduce the narrowing of vessels and promotes blood flow. If you are not trying naturally, i.e.: having fertility treatment, then you can take throughout your treatment non-stop, but PLEASE stop in the 2WW, as it can bring on uterine contractions and therefore make you bleed/have your period.
