Hi. I was wondering if anyone else has problems using tampons. I change them every 4-6 hours, don't sleep in them, and are cautious when I use them. But everytime I use one I get so dizzy to the point I can barely walk around. I get a bit of nausea as well. Maybe I just have an intolerance to tampons? I'm really not sure and worried.. Any advice would be great. Thank you in advanced.
