Hi guys- Sorry I haven't been around as much lately. I've been cycling and posted my update below. I am starting PIO tonight (2 days in advance of scheduled ET)and was prescribed a dose of 0.5cc (25mg) once a day. A google search showed people taking more like 1-2cc. My natural cycle progesterone has only been tested the day after ovulation and the second to last day of my cycle, but was never really over 2-3. What dose have you guys taken? Should I ask for more? Thanks so much and thinking of you all.
