Spotting

Yesterday I had red bloody spotting, which tapered off to brown/black spotting and I'm still spotting today. My back aches a bit between my hips (cramps for me are normally in the front), swollen breasts and my husbands normal spray made me feel sick yesterday.

My period is a week away and I took a test this morning that was a bfn.

I'm planning on testing Friday and Monday.

Anyone had this kind of spotting and symptoms and get a bfp?

Thanks for any response.
