When did I ovulate?!

I started thinking I didn’t ovulate this cycle, because I got positive OPKs on Jan. 5 and Jan. 6 (late evening of Jan. 6 was by far the darkest.) and I hadn’t gotten a temp spike yet. Finally this morning (Friday, 1/10)

I got my big obvious temp spike. It seems really late for that if I ovulated Monday or Tuesday. Any ideas?! This cycle has been a little weird, so now I have no idea how many DPO I am, or when to think my period might show up, or when to test. TIA for any help!
