Melatonin before IVF causing period to be late?


#1

Wondering if anyone has experienced irregular menstrual cycles after starting melatonin? I’ve been taking 1mg in advance our next IVF cycle, and now AF is a couple of days late - throwing off my IVF calendar, of course! (BTW, it’s VERY unlikely that I would be pregnant naturally.)

I would doubt that it is the melatonin - especially a low dose like 1mg. I am on it (3mg) but my cycle is messed up because I had a chemical pregnancy.

if you are in long protocol, it is possible that your AF will be few days later.
i used melatonin 3mg for 3 months and ma AF came regular

Melatonin did not delay my cycle at all and like the other posters said I was also on 3 mg.
