was specifically for an OE cycle that was to be injectible IUI. I don't have experience with this type of suppression with FET. The OE cycle was a bust for that month. Had to completely start over after AF ended.....hopefully someone else will chime in.
With only 1 embryo to transfer I'd be very cautious and wait if I needed to. I know the waiting sucks, but it's better than losing out b/c something is off this round. Good Luck!!
