Had the appt with the RE today and she said that we can immediately start on the cycle for the FET! She didn't have an answer as to why it didn't work, but I didn't think she would. She was also worried that I might be frustrated and that I would want to transfer 2, but I told her that I would only want to transfer 1 (given my already high risk for another preemie).
I asked her about metformin (because I had read that others with PCOS had used it) and she said that she usually only uses it for stim cycles, but that it wouldn't hurt me to try it to see if it will help with my hormones.
So, now I'm waiting for AF to come so that I can start the birth control and get this cycle going for the FET!
