Omg!! Why me??????

So I'm staying over at my best friend house with her, her mom, and her aunt. Tuesday night, I went to bed around 6pm because I got super tired. I woke up around 11pm and went to the bathroom. AF showed signs so I went on and put on a pad and went back to bed. Wednesday morning I get up and go to make my way the shower when I'm stopped by best friend's mom. She tells me AF has showed up over my shorts 😶 she then gives me the hook up with pads. I get to the shower and notice that AF has trailed completely off the pad and up my backside. 😔 I go to bed Wednesday night with a new pad on. Now I wake up 4 hours later and I'm laying on my back. I hate sleeping on my back so idk how is this possible. I turn over to my side and touch my butt to make sure it's not wet. It is!!!!!! Now I'm scared to get out of the bed because I think I have messed up my best friend sheets on her bed!!!!!! My life sucks!!!!!!!!
