Hi Kas
I haven't come across Femarelle so I've just been looking it up.
From what I can gather it contains phyto-oestrogen compounds (lignans) that are synthesised or derived from soy and flax seed, and different from, and cannot be compared with phyto-oestrogens found in red clover (iso-flavones).
I am new to all this so haven't got to grips with it yet but Femarelle acts as what is known as an SERM ie a Selective Estrogen Receptor Modulator, which means it acts selectively on some oestrogen receptors and not others, whereas red clover isoflavones are oestrogenic.
The manufacturers report a lot of studies on their website here:

However the main point about its mode of action is that the studies appear to show that it relieves menopausal symptoms and can prevent bone loss, but does not act on the uterus nor the breast, and so should be entirely safe to use ie it is not a hormone.
That being the case it cannot have caused your bleed - and that was a coincidence! As Dancinggirl says in any case even if it could stimulate the uterus it could not act that quickly.
What I don't understand is why it hasn't been licensed because it would be a fantastic alternative to HRT on NHS for those who cannot take oestrogen. I presume it is because studies are continuing (which the company say) and of course there need to be rigorous, controlled trials with different dosages over a long period of time in order to assess its efficacy and safety, as well as how it might interact with other medications and treatments. Scientific results appear to be promising (re menopause) but maybe conflicting.
It all sounds a bit complicated and I can't take it all in at the moment, so hope I've got it right - has taken ages to find this out!!
The fact that you've had a period though Kas menas your own hormones are still active so you are not yet at menopause, so I imagine your flushes might have stopped for a bit (maybe you don't get them anyway if you're on ADs?) - not sure if you are pleased about this (re the periods) but I would be!
