I bought some fertilaid after reading numerous reviews of it being helpful. The month I took it I started on cd1 and took through out the end of the cycle. I didn't get a pos opk that month. Now it's the next cycle and I didn't get a pos opk this month either and no fertile CM either. I think it worked the opposite on me. Now I am having a 30+ day cycle instead of my 28-29 day cycles???? Help please? ???!!!!??
