I took soy for the first time this cycle. I took 100mg between days 3-7 and it actually made me ovulate later, like CD18 & CD19 I had positive OPKs but still no temp rise. I usually get a + OPK CD15, so I think it's stopped me from ovulating this month. My cycle is only 28 days long. Really gutted soy didn't work as I thought it would give me the same results as Clomid which I needed to conceive my first child
