Sleeping habit? Help!

( Im a Female, 16 yo) I've been thinking a lot if I should share this or not. It may be disgusting for a lot of people. I honestly don't know if it's a sleeping habit or something else.. So.. I get my period.. Ok.. Go to sleep.. Alright.. When I wake up is the hardest thing. My hands are covered in blood. Sometimes is just my nail or just my fingers. I don't know how this happens. Maybe I touch myself when I'm sleeping. Now, if I sleep for a short amount of time it won't happen. This also happens when I DON'T have my period. I know because my sensitive area hurts.. You know when you scratch down there and it hurts? that's how it feels. It happens every time now. I'm from another country, I came here when I was 10. While I was at that other country this didn't happen. It only started happening after I came here (New Country).. I don't know who I should consult this with. I'm a very timid person. The hardest person to tell this to would be my mother. I also don't know if I should go to a regular doctor. I've also tried to find answers.. Online I don't find a thing. I also asked my friends and they think it's odd. I've tried sleeping with gloves before. They help, but it's annoying having to sleep with gloves every day. Most of the time they come off and again with the blood or I touch that area. The blood also only appears in my hand. Everything clean but my hands. If anyone can help please let me know how. I really don't know what to do. (Sorry for my bad English )
