Pregnancy question

M

I got my BFP a couple days ago and found out from my last period I’d be about 5 weeks.

I went for labs yesterday because my tests were faint and they just called me and said my levels were 14 and im looking between 3 and 4 weeks pregnant. They want me to come back tomorrow to run another blood draw to see if it changes.

Should I be concerned?

Also I took a digital last night and it read not pregnant. I took one this morning and to my surprise it said pregnant! My levels must of increased from yesterday then?

I know digis need more hormone to read pregnant.
