On monday I cut just the inside of my vagina with a razor and it bleed a lot at first but stopped after a while and was fine the next day, but yesterday I noticed some blood in my urine, my knickers and on the tissue when I wiped. Im 13 and yes ive started my period. Im not sure if the blood has come from the cut (which I dont think it has), my vagina or my urine but I know its not my perioad because that doesnt start fir another 10 days. Please help me im quite anxious about it!
