Ok not sure if I should post this here or somewhere else like TTC but thought I'd try here.

I get bad cramps, really bad, had a lapra for endo and that helped but I still use heat packs.
Question is can they be too hot? I make mine hot enough that I've given myself blisters (heat pack heated the button on my jeans and that burnt me).

I've been TTC well over a year, and I'm scared that the heat from the heat packs has somehow destroyed all my eggs. I've tried google for this but the only thing that comes up is about men and keeping their laps cool

TIA
