Very early prego sign??? Plz help <3

I’ve been taking prenatal vitamins for a couple months now in preparation for TTC. When my husband and I decided to officially start, I switched from Spring Valley Prenatal (28mg iron) to Ritual Prenatal (16mg iron) to up the quality…I know PRENATAL W/IRON CAN CAUSE GREEN POOP…BUT I didn’t have green poop until maybe a few days after switching to Ritual, which is less iron. No, I haven’t been on top of my leafy greens or anything and there’s no smell, so no infection. I’ve read it could be a VERY EARLY SIGN to pregnancy (literally first days of implantation), but I’m only CD 11 and mayyyyy have ovulated 2 days ago when I had a higher LH reading. I’ve definitely felt severely fatigued (slept 12 hours instead of my usual 5-6) and had a little pink spotting (but could have been from sex earlier that day). So I am confused about what to think! It’s too early to test…any thoughts? Anyone else experience this?
