I see. The only advice I can give is this: if you can go in for monitoring, that will be best. My FS does a postcoital test, where she realized that Clomid caused me to have hostile CM -- google it, but basically it's too sticky and thick for the sperm to travel through. I was even taking the max dose of guaifenesin for the week leading up to ovulation and it was still bad. She also checked my follicle sizes, which showed her that the 50mg dose wasn't having good results on me, so she increased the dose after the 1st month. If I hadn't been monitored so closely, I would have been questioning why it wasn't working for me (CM issues), and I would have been taking too low a dose (follicles not growing quickly enough).
