Light blood and period has already been

My 'period' has already been.. If you'd even call it that.. basically this 'period' was VERY light and I started bleeding on Wednesday the 22nd and the first 4/5 days were spotting, not even enough to cover a panty liner.. then the rest of the days were a very light period not enough to actually cover a pad this time until the 2nd of March and baring in mind my period is only 5 days usually and they are so heavy that I have to wear a pad and a tampon. So that was already weird..

Now bring it back to yesterday I was having sex with my boyfriend and my juices on him were blood tinged and then tonight he was fingering me and his fingers had blood on.. like a really light period. What's going on?
