Well my BFP turned out to be a big fat chemical pregnancy. I suspected as much when i couldn't get a urine test to go negative. The blood tests i had must have caught a low hcg level. My period started late tuesday night. I'm on CD2 so i started the soy again tonight. To those who are taking it, i do think it helped me get pregnant, despite the pregnancy failing. I've been TTC for 11 months and that's the best result i've gotten yet, on just my first cycle using soy. Also, my cycles had been getting long for some strange reason. My normal 28-30 day cycles became 39 and 44 days long over the 2 previous cycles. Even with a chemical pregnancy, my cycle still wound up being only 33 days. I think my period would have come 2-3 days sooner even if the pregnancy hadn't been doing on.
