Soy Isoflavones confusion - please help!

[serah]

This is my first cycle taking SI.
I am a regular 28/29 day cycle, I use OPKs which normally give me a smiley from day 14.
I started SI on CD3-7 inclusive.
This weekend I started feeling nausea from time to time. We also had a road trip which made me feel quite queasy. We do this trip often and normally Im fine.
My chest seems to have expanded overnight - which last time happened when I was expecting DS.
These things normally dont happen to me when AF is due.
AF was due on Friday this week, Im currently 26 and I've started spotting.
I know I missed my O day as I had EWCM on day 12 but started the OPKs on day 13. I never got a positive. My ovulation day definitely came earlier. Dont think we BDd at the right times.
However, I still feel nausea and my chest is v v sensitive, plus I'm spotting too.
Has anyone else had the same thing on SI before?
I did POAS with FRER yesterday and it was negative
Do SI make your body react this way ?

Yea, SI can cause those symptoms. I only used it for one cycle, I did end up pregnant. But I had some unfavorable symptoms that made me not inclined to do it again, even if we were not pregnant. My boobs were sore my whole cycle, I was really bloated after taking it, and it made me really emotional. I was on and off nauseous after ovulation as well, but it went away even though I was preggo...that pregnancy only had motion sickness. Overall, I didn't like soy at all.

You still could be preggo, if there was any BDing within 5 days leading to O. Some people don't get positives until later. But I wouldn't necessarily deny that SI can cause some weird symptoms throughout a cycle.

I actually did get a BFN with my DS and got my BFP about a week later..I'm trying not to get my hopes up that this'll turn into a BFP but not likely I'll try soy again.

The soy has caused some weird things to go on with me too...serious O pains, BLOATING (in caps because I look ridiculous), sore boobs. This is my 3rd cycle on it, and I'll probably drop it if I'm not pg this month...good luck serah!

So far the spotting has remained just that. Brown mainly v little red. Don't wanna get my hopes up but am just saying..

Soy can make you have pg-like symptoms.
