Advice please!!

At 12 dpo I had a faint but positive pregnancy test. On 13dpo I had red spotting, it was bright red but never filled a pad it was just there when I wiped all day long. It was red spotting for about 16 hours and then turned pinkish brown for another few hours and nothing when I woke up Monday morning(14dpo) It only lasted the one day. Monday 14 dpo I took another test and it was much darker than the one Saturday. Is that a good sign if it got darker after I had the bleeding? I had beta hcg drawn today but haven’t heard back yet. Anyone experience anything similar and everything be ok? I’m so worried!!
