I am an 18 year old sexually active young lady. My boyfriend and I have cut back on intercourse. It has been 3 days since the last time we made love but yesterday we got a little friendly. He fingures me and right after I began to bleed. At first I though I just started my period. But as the day went by the blood turned from red to brown( as if my period was going off) and this morning the brown blood is coming out more and more. My boyfriend did not hurt me in anyway. So, I'm just a little nervous to what this could be!

If it was bright red fresh blood appearring, then yes, his fingernails are probably too long and the vaginal walls are very sensitive to injury. Just make sure he keeps them trimmed and clean.

There cant be too much brown blood appearing and it will eventually ease off.
