Ovulating normally but in clomid

Maya

I ovulate every month. Confirmed by kit and bbt. I went to see RE and he put me in clomid 100. When he did my ultrasound he told you I can see you ovulated already it was cd24. He also said your follicles are already bigger , are you sure you have 28 days Cycle. This shows like you might have 24 days cycle he said.

My cycle is always 28. Have any of you have perfect period, ovulation and yet started on clomid. My major issue is low AMH. Thanks
