2 periods in a month, started first round Clomid yesterday

Anyone had this happen? I had a spotty 3 day cycle end of July (guessing my lining didn’t shed) so then ovulation day comes around and I pour blood for 4 days. I go to the dr, have an ultrasound, everything comes out clear. This is my 9th month ttc so my dr stared me on 50mg Clomid, days 5-9. (We think.) Has anyone been lucky with Clomid with an irregular cycle? This is my first irregularity.
