Need help. Can I be having an ectopic?

Sa

I ovulated on February 10th or 11th.

I have been spotting brownish blood since Sunday, approx 7 DPO.

Yesterday, approx 11 DPO, the spotting became heavier so I thought to call it AF.

bleeding continues. It is reddish-brown. But THICK, like sludge.

I'm cramping. I started feeling light headed, now the night of 12 DPO or CD2.

HPT all negative.

cervix is so high I can barely reach it.

Is it too soon in my cycle to have symptoms of an ectopic? I just don't understand the color or consistency of my bleeding. The cramp pain isn't touched by midol or ibuprofen.
