Always have regular 28 day cycles except for one month where it was 25 but this month I started my period on CD17?!

I think I’m doing too many vitamins only thing I changed was to increase DHEA and started taking Biotin! I immediately stopped both a few days ago when I noticed the terrible acne and sleep issues but I think it’s too late I messed up my cycle!

Please let me know if you experienced similar stuff?

What’s worse is the clear blue advanced never picked up ovulation this month even though I had sore breasts and 1 day of ovulation spotting!

Please help!
