I’ve been cramping really bad with a bunch of tampon brands and braking out in hives from different pad brands as well and tonight we went up to the Er for cramping that woke me from a dead sleep and painful I couldn’t move and turns out I’m allergic to the tampons as well.but b4 I had my son o had no problems with any allergic reaction like this. I not sure if I should go into see the doctor when I’m able to or just let this play out they didn’t seem to conserned at the Er but obviously can’t use tampons or the pads I have the rest of this cycle.
