Positive OPK ... day 7 of spotting/AF? ... help!

So confused guys and wondering if anyone had a similar experience:

- periods are normally 5 days (w/ 2-3 days of heavy bleeding)

- cycles are normally between 32-35 days (w/ a couple 38ers in there during times when I was out of my routine - traveling etc)

This past month I didn’t have any bleeding until CD40 and that was minimal spotting and now I’ve been bleeding/spotting since (7 days). Bleeding is more on the TP when I wipe and only a bit on my liner each day.

All BFNs when I test (last one was 3 days ago).

Chalked it up to a weird cycle - the bleeding started lightening up so I took an opk test this morning to get back to tracking and it was super dark ::

What the heck is going on 🤷🏼‍♀️

Plan is to test both LH and HCG in the morning just to see... stay tuned!
