TTC 11 months

My husband and I have been trying for baby #3 for 11 months now. We never had problems with the first two, so I spoke with my OB and he mentioned that I might not be ovulating enough. I am only 27. I am to get bloodwork 7 days after I ovulate which was last Friday to see if I am ovulating enough. If I am not he mentioned me taking Clomiphene but could increase my chance of having more then one. Has anyone had more then one that has taken this fertility pill?
