What causes hostile CM? I'd be looking into that to address the problem. It could mean some dietary adjustments and being careful about how you wash down there- not too much soap. EPO is fantastic, and as an added plus it is great for hair and skin too. I don't have hostile CM but took it while TCC my three pregnancies and noticed a definite increase in egg white cervical mucous- the really good stuff. You take it orally from day 1 of your MP up to ovulation.

Lots of girls here also love preseed.
