What in the actual F???

So per Glow i am 3 days late but per Me lol i am 4 days late or at least i think i am. My "period" started yesterday, i put on a pad and it was a light to medium flow, which is weird for me i usually have a heavy flow the first day until about the 5th day. I am currently on my 2nd day and hardly anything is coming out, only mainly when i wipe. I could easily put on a panty liner and id be okay for the rest of the day. i have light cramping, my boobs still hurt (they usually stop hurting once AF starts), and i am also bloated. Honestly i am extremely confused. Me and my fiance are currently not trying but not preventing either. Have any of you gone through this? if so, was it your period just being weird? or did you get your bfp?
