Thought I would report back on the Soy Isoflavones.
I had my usual spotting but slightly earlier at 9dpo. On Monday (12dpo), I went for a run in the sleet and noticed my right hip was sore afterwards. This is something I suffer with in pregnancy. I also felt feverish and my nose felt really blocked (with big bogies, not snot - sorry for tmi). Tuesday I just felt really odd, hot and shivery, didn't want chocolate (unusual) and smelt someone's breath on the train. Yesterday, same, I felt like I had a glow or that my body was electrically charged. I'm convinced it was the pregnancy hormone.
However, at 5pm yesterday I noticed a load of brown discharge and then AF started straight away. I never come on at this time, I always start AF in the morning.
I am not a tester as I know when I know (I've been pg 4 times excluding chemical pregnancies). I wish I'd tested now so at least I would be sure but I'm pretty sure this was a chemical pregnancy. And can only assume it was down to the Soy Isoflavones so I'll be taking them again this cycle but starting at cd4 instead of cd3.
