Help!

I need opinions please. I started Clomid last month day 3-7 and estradiol day 5-8 I believe. AF came 3 days early and stayed a little longer than usual last day was Sunday and looked brighter than usual. It is now Wednesday, I went to the bathroom and noticed blood on my panty liner, it’s bright not as dark as it usually is for spotting. Would this be the effect of Clomid and estradiol? Waiting on dr to give me appointment
