Implantation bleeding or period

Okay, so I have very heavy, and severe periods to the point that i’m in so much pain I can’t move and i’ll fill up a tampon every other hour (sorry for Tmi) And my periods last 6-8 days sometimes 10 and my cycle is about 32 days, but I just had what I thought was a period but it started off light (Which never happens) and then got heavier, but would bleed off and on for 5 days, only 2 days it was a little heavy, but it didn’t even fill up a pad (Only one day throughout the bleeding it could have filled up the pad.) it came about a week after ovulation which I experienced light bleeding for 3 days during ovulation. I’m really confused and would like to hear y’all opinion and also stories. (Also I have 3 faint positives, but i’m thinking they are evaps but each time I test they get darker, but they show up after the time limit.)
