Help! False positive!?

Karlee • Boy Mom Survivor 💙😂

I am 11DPO (i think) and I just got a positive pregnancy test with a digital first response. It was a clear "YES". I was NOT expecting it. I took it as a joke. Yes we are trying but I didn't think we had good timing this month because husband was traveling during part of my fertile time. How common is it to get a false positive??? I will take another one tonight but could it be wrong?? I don't want to get my hopes up and I have like zero symptoms. I definitely thought I was getting af soon.
