Slight Bleeding Two Days After Fingering?

It is two days after my boyfriend has last fingered me and today I noticed a little bit of blood, and I'm not sure if that is completely normal?I'm currently a little bit concerned. I am not a virgin, so I know that it is not my hymen. My boyfriend and I had sex twice four days ago and once three days ago, which is the first time we have had sex in about a month, but there was no bleeding from that. I am a little concerned that it could be implantation bleeding, although I've done a lot of research on that, and I don't seem to be within the time frame that implantation bleeding would occur, if it even would considering that it is not that common. That is still my main concern at the moment, but I also feel that I might be able to contribute the bleeding to being fingered? My boyfriend and I do get sort of rough at times, and he does get rough when he fingeres me and he will do it for a while. Two nights ago we were fooling around and he was fingering me and it got pretty rough. This happened a few times that night, and by the last time he did it that night I was pretty sore (which is competely uncommon), but I was also feeling a little pain and felt like I really had to pee even though I just had about an hour ago. I went to the bathroom and it burned liked crazy, and I barely peed at all even though it felt like I really had to. This feeling continued on that night. It seemed to have gone away the next morning, although I still felt kind of sensitive and sore, but then later that day I kept getting this extreme urge to pee, only to go to the bathroom, barely pee at all, and be in pain. I looked it up and found other people with the same issue after being fingered, but also found that it could be a UTI. Now today the symptoms with having to go to the bathroom and whatnot have seemed to have subsided, but when I went to the bathroom this morning, I noticed what looked to be a drop of blood in my urine. I did bleed ever so slightly the night that I had been fingered, but had not bled since then until this morning. I didn't have any other signs of bleeding until tonight when I went to the bathroom, and when I got up I noticed a bright red spot of blood on the toilet seat and there was a little bit of blood when I wiped myself. I'm not due for my period for another 9 days, so I'm pretty positive that it is not that. I am also pretty positive that the blood did indeed come from my vagina and was not blood from my urine. So could it be possible that this could be from the fingering?
