Fertilaid and delayed ovulation

Has anyone ever taken fertilaid and had bad reviews on it? As far as it throwing off your cycles, delaying ovulation, etc? I started taking fertilaid a few days before my fertile week which was supposed to be all this week. (So I started taking it last week) I have yet to ovulate this cycle. Now glow has pushed back my fertile week to this upcoming week with hopes that I ovulate next week. Has anyone else experience this? I normally would have ovulated by now and I havent. Anyone have an idea why this would happen? Im just worried that these pills messed something up with my body. Thanks!
