Can Clomid make your menstrual cycle abnormal?

I am on my second cycle of Clomid cd 3-7. My first month I began my period on day 15 and now on my second month I have began on day 18. Is it possible that Clomid can make your menstrual cycle abnormal? Can it take months to be on Clomid to have regular period? I’m happy to know I am ovulating but, I’m frustrated that I am getting my periods earlier than normal. Is there anyone that can help me?

Ya I think they say it takes like 3 months to regulate, my first clomid cycle was 21 days and my second one I didn't ovulate until day 19.. so I think it just needs to regulate your body..
