Bleeding after a BFP

Here’s my story...just looking for advice or similar situations.

November 2019 it was confirmed that I was having an ectopic pregnancy. We were TTC our second child for over a year. I had emergency surgery on my left tube. When they got in there, they said the tube already ruptured but it was salvageable. So they saved it and blamed the cause on “ simply bad luck”. I waited out the two normal period cycles before we were allowed to try again like suggested.

The last week of January 2020, I had a BFP on a few tests. 5 days late on my period until spotting started which then turned into a normal period. I took another test and the lines were darker.

Is this a chemical or a miscarriage?

Could it be another ectopic?

Should I wait it out or call the dr. Office tomorrow when they open?

We want a healthy pregnancy so bad our hearts ache. Did anyone have similar situations or happy outcomes? Thank you.
