Can someone please explain what clomid does? Side effects, how quickly it works, etc. My doctor said today that she wants me to use OPKs for three more months and if no pregnancy by then she wanted to start me on Clomid and do a semen analysis on my husband. I have two children from a previous relationship, my first daughter taking two years to conceive. He has no children, so we’re getting a bit anxious. Doc said she could go ahead and start me on Clomid if I prefer. I just wanted to ask for personal opinions and experiences first. TIA!
