Hi Blaze....

I had my last IVF 5 years ago & both times AF came early ( I think I'm lucky ' cos I would have been devastated if I was late then wasn't pregnant) BUT , in my case in the whole 5 years since ,AF come's between 28-31 days every month, no telling when , which can sometime's be frustrating when trying to pinpoint ovulation
Dr's are at a bit of a loss as to why & when seeing as before IVF I was day 28 on the dot ??? I suggested going back on the pill to try & regulate my cycle they said a very strong no !!! I still after all this time would like to try that , might chat to my GP now that it's on my mind again !!!!
Good luck
