Confused!

I stopped my BC December 9th. Bled Dec 10,11, nothing 12. Blazing positive opk the 16th. had sex day before, day of and day after. Slightest light pink spotting 22nd. Like light pink only there when I wiped. According to when I ovulated I should get my period December 30th. If I was still taking my BC I would have gotten it yesterday... which I did anyway? I think? I’m bleeding but not super heavy. Enough to need pads and tampons though. Bright red. I’ve been taking pregnancy tests- all negative last couple days. Is this my period?! Maybe I will ovulate normal this next month?! I’m so confused 😩 I’m a mom of 3, this isn’t new to me. But I’m just not feeling as in tune with my body right now. Ugh.
