Am I pregnant?

Erica

I had a miscarriage April 29 and haven’t gotten my period yet. I bled for 2 weeks. I took a pregnancy test and it was positive. We only DTD once. I haven’t had a cycle since. If I am pregnant, would my due date be from the date of conception? Or is this lingering hormones? It’s been 4 weeks since I’ve stopped bleeding. I don’t want to get my hopes up as I’m nervous of a sad outcome.
