Good morning, I am new to all of this too. I was officially diagnosed with PCOS in the fall. We did all of the other tests and all thats been found is I don't ovulate. I started clomid 50 mg on day 3 of my cycle (December 30) and then took it for 5 days. When I went back to get an ultrasound and see if anything happened, nothing. My doctor immediately had me start 100 mg for 5 days. I am currently on day 4 of that. I go back Tuesday to find out if anything happened this time and if so schedule my IUI. I know they say clomid makes you moody, but I feel all over the place. Does anyone know how long it takes for the side effects to go away after your cycle is over? Also has anyone else had their dr start them up again so quick after a failed attempt at ovulation? I am really appreciating reading this site, because I'm not feeling in all this.
