Hello. I'm a 21 year old girl & I've been with my boyfriend for 5 years. Yesterday he fingered me, but it wasn't the first time. However, yesterday I bled a little. It was very light pink. No pain. When we finished his hand was covered with red dots, similar to dirt, red dirt. I'm 2 weeks away from my period, so I don't think it was about that. After a while, I checked again, there still was pinkish blood on my underwear. He offered to check if there was something. He couldn't see anything. He stuck his finger very slowly to see if there's still blood, but there was nothing. However, it burnt when he stuck his finger. Today the pinkish blood turned into a yellowish color. Can anyone explain what it that please? Thanks.

He probably "knicked" you inside a bit, very tender lining in there. Next time make sure he checks his nails for length, hang nails, etc. that is why the look of "new blood". Your own personal antibacterial in your vaginal tract will take care of it.
