That's Interesting. I haven't experienced the same, but I have taken zinc a bunch of times recently, because I kept feeling like one was coming on. I don't think it was related to my O, though. PP makes sense about temp spike...
You might avoid the green tea, though. Here is info from the TTGP link at the top of the board: "
Don’t drink green tea during the 2ww because it could cause uterine
contractions which might impact implantation.
make sure you are drinking the green tea at least 4 hours removed from
taking your prenatal vitamin- it can block the absorption of folic acid."
Hope you feel better soon!
