I have been reading that AF can get messed up after artificial (IVF) cycles. My clinic have advised that we can only start looking at my next IVF cycle after a natural AF cycle. I had a failed cycle in May (no blasts made it to day 5), AF arrived very quickly due to the artificial cycle. My natural cycle has not yet started, I am now on day 57, my usual cycles are 32 days, so I am 25 days overdue. What are your experiences?
