Hey Lulu,

I didn't do full on IVF but did IUI. I can fall pg too but find it hard to sustain a pg. I was an ok responder to the meds - low dose and constant monitoring. I never got more than 1 mature follie. Once we had confirmed ovulation and the proceedure was done, they did blood tests to check my progesterone levels (what help to sustain pg) and each time I was told to do the extra prog. injection. Sounds like they are going to see how you respond to the meds and offer prog. supplements based on your response (checked via u/s & bloods).

Hopefully some of the more experienced IVFers will pop in.
