Anyone else this month????

So this month my period was a few days late (according to eve. I usually give a day or 3 before I start worrying cause yknow apps aren't exactly In tune with out bodies.) But it was also MUCH lighter compared to last month. Last month I was heavy, changing pads every 3ish hours and this month every 5-6ish hours. Normally I'm about every 4ish hours changing for reference. Though lately I've not been eating as much. In terms of meals but snacking here and there. Is this a hormonal thing or am I tripping? Also has this happened to anyone else this month?
