Digital positive at 3 weeks?

Zoe

Based off of my LMP, I'm 3 weeks 1 day today. I got a digital positive yesterday, normally with my pregnancies the earliest I could get a positive was at 3w4d and definitely wasn't with a digital. My son was a twin (ended up a singleton pregnancy) so I'm concerned about this being another multiple pregnancy.

Has anybody had a digital show up positive this early? What was the outcome?
