Repost plz read

So I had a miscarriage/D&C on the 24th of December,, I was 17 weeks and had a ruptured membrane..

Well I took a test yesterday with smu and got a positive.. I took another today and its faint(neg),, well I took a frer and its postive..

Is it possible that the frer Is from left over hcg?? Also I used neg cheapie with same urine as frer

** also why would my test from yesterday have a sudden surge???

°postive cheapie yesterday w/ smu

°frer today

°Faint(neg) cheapie same urine as frer

°collage starting from 1/2/20 -1/21/20
