Tekah,
Sory to hear your bloods were not so kind, I have done a few IVF cycles 19 all up and ad many different responses with the prog pessaries. One I got AF whilst still on them, one I got a BFP really early day 10ish and one I got a BFN and then had a BT done which came back positive.
Good luck with the flares, they worked better for me than down reging
