So heart tree, you took soy iso this month too? was it your first month taking it? I've been taking vitex past two months, but considering switching to soy iso for a month.... I love the vitex though, so not sure what to do! But I like to feel like I'm doing SOMETHING.... ya know!
It was my first month using soy. It caused me to have 2 false positive OPK's and lots of spotting for a week starting at CD13. I use the smiley face OPK's so it wasn't like I was misinterpreting the OPK lines. I ovulated on CD26 which is when I normally ovulate. I also had a true positive OPK on CD25, 26 and 27. And my temp rose right around then too. If you want to look at my chart, it is at: https://www.fertilityfriend.com/home/21867b
If you want to use soy, make sure to do your research. There is a lovely thread where they can offer lots of advice. Here is the thread: https://www.babyandbump.com/ttc-buddies/179679-any-soy-ladies-out-there.html Let me know if you have any questions about it too. I don't know much about vitex, so can't offer any guidance there. Good luck!
