Stupid hormones

I'm so pissed . I started my period 9 days early . I know for a fact I doesn't ovulate. The only thing I can think of that would mess up my cycles is my thyroid medicine which my Dr lowered. But I'm gonna talk to him bc how can ttc is my cycles are messed up. This month I only had a 18 day cycle, I usually have a 27-29 day cycle.
