I hope that you have much success with Clomid the first time around. Here is what I know about it/my experience:
I had a lot of ovary pain while on Clomid. The first time was the worst. It was not unbearable but it was really odd to be able to feel so much. Clomid can also extend your cycle, cause headaches, mood swings and hot flashes. Those are fun.
Will they be doing any monitoring with this cycle? Were you checked for cysts before you started? It's very important that you are checked because if you do have any cysts, Clomid will make them bigger.
How long have you been ttc? I know that you will find a lot of support here. The other girls will surely have more info for you. I hope this helps.
Good luck!
