I was penetrating my g/f with two fingers, knuckles pretty straight, reaching around her cervix when suddenly she felt pain, looked, and there was a lot of blood. My hand and wrist were covered with bright red blood, she drained for about ten minutes and it has now stopped. One chunk did come out, that when left in the toilet has reduced from a red clot to a clear "skin like" consistency. I reached in again and didn't feel any obvious tears or changes in her cervix. Obviously she's sore. If bleeding has stopped, should we worry?

If the bleeding has stopped, and the pain has all subsided in 3 days- no worries. She can take tylenol for pain. Heating pad might help. No penetrative sex-3days. And be more careful in future. You likely just caught a fingernail or hangnail on her cervix skin.

Great point for anyone planning finger penetration....trim those nails and make sure they are clean.
