Onto a new month of TTC- Soy iso anybody?

CD1 here... AF showed her ugly face with a vengeance today. Anybody here take Soy Isoflavones? I took them for the first time during my last cycle, but I took them later than the recommended timeframe (I think it was like CD8-11). I normally have long and irregular cycles, anywhere from 30-55 days...and I don’t think I ovulate on my own most of the time. This last cycle was 36 days so not terrible, and I 100% DID ovulate as evidenced by an ultrasound by my GYN.

Does anybody have any success stories or reviews of soy iso? I’m considering taking it CD 2-6 this cycle, so starting tomorrow
