Clomid without AF?

Megan
Hi! Just joined the group. My doctor is leaning towards me having PCOS. Just have to do a few more tests to get the diagnosis. She said if it is pcos, then she will start me on clomid to hopefully get pregnant, or at least ovulate which will make me have a period if I don't get pregnant. I haven't had a period for over 4 months. I always thought you'd have to have a period first to start clomid, but apparently not according to her. Has anyone else been given clomid without being at the beginning of a cycle??
