Help!! TTC: Very strange/light period

I am usually a heavy bleeder during my periods. But this time, I am bleeding but very light and on and off. I am hungry more, nauseous at night, headache, mood swings, extremely bloated and gassy. my period last 6 days. Day 3-4 I didn’t even dent one pad. I usually go through 3-4 full pads (thick pads) and I didn’t even dent one. I switched to the pantie thinners. Today is day 5 and I’m bleeding again as if it’s the first day. what could this mean??

BTW...

It stated my ovulation date was June 23rd and we tried the 20th, 22nd and 23rd and I got my CM the 27th. And my “period” the 8th of July (like it stated).
