First Time Clomid User Advice?

Brandi
So I'm super nervous about starting clomid. I have unexplained infertility and was prescribed 50mg of clomid. Waiting for Af to start and will start clomid on CD3. Is there any advice anyone can give me while using clomid? The do's and don'ts. I've heard that clomid can thin out the lining of your uterus. What can I do to prevent that? Any advice is helpful.
