I, honestly, prefer pads, but my mom always gets tampons. So, last night, I had a tampon in since 18 and, around 21, I fell asleep. At 3:50 (that is super early for me), I woke up, got a drink, and took it out, due to frgetting to do so. I had it in for around 10 hours. Now it hurts super bad, my cramps, and idk what is wrong.
