There are past thread/replies on clomid... U can read them too.
I am taking clomid, this is my 3cycle... I have pcos and not able to get pregnant... Clomid caused me slight blur vision but only for 2 or 3 days while taking it, after that no problem. It has definitely make my period regular, since I am taking it with metformin(another drug). I also had ovulation with it.
Right now I am ttc, have not tested for pregnancy yet. But it's good to take if u have no ovulation, it may or may not help, but it's good to try it out... If u r ttc like me...
