Advice please!!

Saturday at 12 dpo I had a faint but positive pregnancy test. On Sunday 13 dpo I had bright red spotting, but it wasn’t enough to fill a pad it was just there when I wiped all day long. It was red spotting for shout 16 hours and then turned pinkish brown color for a few more hours and then was gone 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 I took Saturday. Is that a good sign if it got darker after I had the bleeding? I had hcg lab drawn today but I haven’t heard back. Has anyone experienced anything like this and everything be ok???
