Bunnie23 and Joaniepat
Here's my experience, though Joaniepat I really, really hope the info you've been given is right because I want it to be right, but my experience is that I'm getting migraines with vaginal estradiol. I'm not using Gina, but it does look like the ingredients are the same as my prescribed vaginal estradiol.
Bunnie23, what I can tell you is when I first started using vaginal estradiol I got migraine and sensitivity to sound. Each time I stopped using it, it went away.
With that said, I've got migraine at the moment, for the last 5 days and I'm not using vaginal estradiol. I have been told my oestrogen is too high, so I'm reducing the patch, then I'm hoping I might be able to use vaginal estradiol again, but I definitely got a reliable pattern before with it, and hence not using it.
At the same time, there was a 5 month period where I tolerated it well.
Not wanting to contradict Joaniepat, I know what she's saying has also been said to me by a doctor. But it's just not my experience. I hope I'm wrong, I want to be able to use it. Just sharing my experience.
