I fell asleep with it in at about 10- some up at 5 in the morning. I know my math is a little bit off but I'm really scared. It's only been one day and I feel fine. I used them today again but should I switch to pads for a while now? I don't know how to tell, I don't have any flu-like symptoms but will I? I'm under the age of 15 so am I at a higher risk? Someone please help me!
