Periods after Clomid?

I've always had really irregular periods so the dr put me on clomid. I just finished my third round and unfortunately my period showed up but for the first two days of it I bled enough to use a tampon. Not like usual where I needed to change tampons often. Now with it being the fourth day it's pink when I wipe but that's it. Has anyone else experienced weird periods after clomid? I've always heard the horror stories about how awful periods are but mine are practically non existent now.
