Very serious Question

Darius

So I missed my first 6 wk appointment so I scheduled it when my baby turned 3 months long story short, I was going so I can get on birth control but my doctor told me after I left my pregnancy test came back positive. She stated that after it sat for a while she seen it was positive! But wants me to come back to check she think it could be a sign of a early pregnancy. I hope not but have this happened to anyone?? Please help!! Yes I had sex twice but I thought we was careful
