I'm mid-50s in R1P3 (don't have this day thing down, but I'm on day 11 of P3). I still have hot flashes. Mostly at night/early early am (3-4). I don't know that HCG made it worse, but I do know they were and are more frequent. I also have hypothyroidism and on synthroid which could be another extenuating circumstance. The nurse practioner I saw told me in rare cases women in menopause have started their periods again and it could happen. HCG is used (approved by FDA) for fertility treatments, so yeah, I guess the hot flashes could be a part of that since it's hormonal. Other than that, I've had no "menopauseally" issues at all. (I know, I know, that's not a word. I do/did Subq injections. Have already ordered everything I need and planning on doing 2 more rounds (I think I will need that) on my own this time. It's worth those nasty hot flashes to me.
