Need advice please

Hey so me and my partner have been "trying for a baby" for the past few months, not really trying like others do as I don't use ovulation tests or anything because I know I would become too obsessive and stressed out. We already have 2 kids so we just hope for the best lol. My cycles for a while we're all over the place I was having really long cycles but my last few were normal 28 day cycles but the bleeding was lasting a week or up to 10 days every cycle for the past good few months. I really thought this month I could have been pregnant as my period was late. It was due on th 20th of April and I didn't get it until the 26th. It started off a but like spotting I had no cramps or anything then the nest day it was a bit heavier still no cramps. I was using tampons and (sorry tmi) they would usually be saturated with blood and this time there wasn't really any blood at all. I've still had no cramps as well, usually I get very heavy periods and clots but this time I didn't. It ended last night so it wasn't here as long as my other periods. I'm just confused I've never experienced this before if I had of bled before my period was due I would have thought it was implantation bleeding but as it was late km just not sure what to think
