Lastei

I just got off my period and it’s been a pretty long period like 7 days heavy flow and 2-3 days were I had a little bit of brown blood. This morning checked to see if I had blood and my panty pad was clean (no blood). So me and my boyfriend decided to get some action yenno, he fingered me and it’s been awhile since the last time and it was better than other times ( he said that he felt something like he was hitting a bone or something). But getting to the point I got home and checked my underwear and I had a blood stain, NOT BROWN BUT RED. What can this possibly mean???????
