I'm currently 4 weeks pregnant and I went to the doctor yesterday for a blood test. She called me back today and said my levels were low, 94. I was just wondering if anyone else's levels were this low at this point and everything turned out okay?

I'm worried because I had a chemical pregnancy in December and I've been having lower back and stomach cramps, almost feels like I'm going to start my period at any moment. Is this normal?

These are my tests from Monday, yesterday, and today though. It seems like the line is getting darker though so idk what to think.
