I'm 13 have been on my period a while, started 2 days ago everything was normal, then this morning it was very bright red and disturbingly sticky, also I could sit on the toilet and it would run all the way to the bottom like in a stringy way, then it wouldn't stop until I wipe! Also the blood will jot come out in a sanitary towel will only come out when I have a wee? really need help, does anyone have any advice! All would be very appreciated, thank you!
