Clomid question...

So I took clomid for the first time around the end of April (100 mg). My period was supposed to start May 23rd and started the 24th of May and lasted 5 days instead of 7day. Did a blood test and was negative. My doctor said that from the first cycle I had 3 follicles but enlarged ovaries so I was not to take any clomid during the cycle that start on the 24th of May.

I just did another ultrasound on the 20th of June and my period was to start on the 21st of June but is now 2 days late. He wants to start me on the clomid again cuz my ultrasound was showing no cysts or enlarged ovaries.

My question is has anyone else had these issues and what happened?
