So first I have irregular periods. I've been taking soy isoflavones to help regulate them. I take a dose of 100mg a day for five days each month. I started that in November. On February 19th I started af. I thought it was actually IB because it was brown. I continued to spot for 10 days. I have always had a heavy flow so it was a bit odd. I tested so many times as this is #1 TTC so I'm anxious. I received a BFN each time. So I'm assuming that was just the soy. So that af ended March 2nd. On April fourth around 9pm I wiped and got a pea sized amount of blood. Assuming I was going to just spot again I put a pad on and went on with my day. About two hours later I went to the bathroom and got the same thing. Since then I have not had anything else. Is this Implantation bleeding? Or could this be from the soy?
