Hi menopausalalways,
I just saw your post. I don't come here as regularly as I used to do so sometimes I miss stuff. Anyway - I have never tried CleanMarine or Menomin. But I do take Femarelle and wrote about it under "Alternative Therapies" under the topic "Phytosoya and Other Naturals". I wrote quite a detailed post so won't repeat it here but I have been taking it for just under 5 months and it works for me. I haven't had any bleed on it. But having said that, I am now 54y, having started my menopause aged 47y so I imagine that it would be unusual for me to start getting periods now (I had my last ever period in September 2019).
Hope that helps!
