Bleeding a few days after my boyfriend fingered me..

So I’m having a little bit of a dilemma. I started my period on Dec 24 but I was trying to stop it from coming on so I put i my nuvaring the moment a saw a twinge of blood. This did not stop my period and I ended up keeping the nuvaring in throughout my entire period which lasted 7 days. I took the nuvaring out and threw it away on the last day of my period. The day after, while I’m still kind of spotting (brown blood) from my period, my bf and I have sex. He ends up fingering me until I orgasm. After we finish, I go to the bathroom to pee and notice a twinge of red blood on the toilet tissue. This is sometimes normal after he fingers me and usually stops after a few hours, so I put on a panty liner and go on about my day. Well, the next day I’m bleeding again as if my period is still on to the point where I have to wear a pad. This was two days ago and I’m still bleeding. Not as much as when I’m on my period but it’s still way more blood than regular spotting. And the inside of my vagina feels sore. I don’t want to call the gyno just yet but I might have to. Has this ever happened to any of you before?
