Irregular periods after fertility treatments??

Nicole • hi all! Mom of 2. 2019&2022

I’ve done 3 IUIs with follistim/ovidrel in March, April and May 2018, has anyone else had irregular periods after fertility meds?? I used to be like 29-32 days every cycle and since then I’ve been all over the map, July was 41 days and then 38, 44,28 and this cycle I’m on day 32 and AF nowhere insight! It’s so frustrating!
