Hi Lemondrop.
Don't worry, it'll be ok I'm sure. You'll make your anxiety worse.
I'm on femoston conti, and I've been known to double up. But had trouble with too much of the progesterone, (gave me breast pain) when I did that, so I now take one and half mg of the Femoston,
Plus 1mg Sandrena gel. The progesterone in the femoston suites me fine, it's the best I've ever had.
You never know, your foggy brain may improve straight away, and your doc has proven to you that there's nothing seriously wrong with your brain, so to me, it may be the northisterone doing it, just like Femseven patches caused me terrible migraines for months on end.
I know how scary it is, stressing over getting worse , or going back to where you were before, but I think you'll be fine on the femoston.
Good luck, keep us informed.
