Implantation or AF...? Why positive OPK’s?

I am beyond lost. I’m new at TTC but fairly confident in OPKs so far but I’m just stumped:

I ovulated 5/26, had sex 5/24-5/29

After ovulation opk dropped as it usually does. (See pic)

My CM has been all over the place and cervix has stayed high ( not my norm) from at least 6/4 to current.

On 6/6, 6/7, 6/8 positive OPKs and than I started spotting 6/8.

But it’s not my AF normal appearance,

I always start first thing in AM and it’s always bright red. This is mixed with CM and just seems off.

Last 72 hours I have also had awful headache, fatigue and 6/7 the nausea tipped so harsh I couldn’t barely tolerate it.

So I’m just trying to understand what is going on. I made a chart like picture to help if seeing positive OPKs actually mean anything right now.

And BFN 6/5-6/8

Update:

AF arrived in amplification 🚼,

till next opk, baby dust to

everyone!🌈💖
