Not sure what’s going on...

My period is due on 6/16 but today when I wiped I saw this really dark dark brown almost black color discharge but really small amount nothing how some women describe IB.. right now I’m having like period like cramps.

I ovulated on 6/1 and I did the baby dance on 5/30, 6/1, 6/2, 6/3 And I did have creamy discharged on 6/4through 6/6. My boobs still hurt and I know this maybe be progesterone but any one you ladies get BFP with this situation.

Oh and I took a test today and I got a BFN.
