Hi ladies!

So I've always used pads for my monthly visit and recently I've gotten super grossed out with them bc it's so hot out. So I figured I would switch to tampons. I used to wear tampons bc i was in my swim team in middle school so my vagina knows the feeling.

Today I decided to make the switch and I put my tampon in and it was all good and no discomfort. About 20 minutes later I went to change to my swimsuit and there was blood on the string and in my panties. I moved my lips around a bit and my vagina started burning and it wouldn't stop until after I took the tampon out (and it was almost all bloody by that time). I normally have light periods and I've never experienced this burning feeling with a tampon. Is this a normal thing? Should I see a doctor? I need advice.
