EWCM on Clomid

Jessica
I have had long irregular cycles since a miscarriage in November and my OB just prescribed Clomid. She told me I could start right away even though it was day 23 because I knew I hadn't ovulated yet from charting bbt. I am on day 4 of taking it, so one more day and I have EWCM. Is it possible to ovulate on the days that you actually take clomid?
