Faint BFP but Red spotting when i wipe

Nysh

Hi

For past 2-3 days I’ve been having faint bfps and today this morning day of my beta test I tested BFP with my morning pee but when i wiped i saw dark red blood first then next time i went to the bathroom it was light red/ pinkish. I have been having AF cramps on and off though.

Im also taking Prometrium 2X a day vaginally.

Has anyone had this and had a successful pregnancy or am i out.
