how many weeks am I?

Hello, so I am expecting my first. Let me explain a short story. So my periods have been irregular my whole life, I get mine every 6 months. So I had my period March 24th- April 2nd 2017. 8 days later on April 10th was the first day since my period I had sexual intercorse, and every other day since April 10th I would still be sexually active. 20 days after April 10th (so April 30th 2017) I had decided to test and it had said pregnant (clearblue digital and had taken 3 that day) then the next day (May 1st) I had my doctors appointment and she did a urine test and blood test and called me that Wednesday 2 days later and said I'm definitely positive for pregnancy but I am very very very early. And didn't exactly say how far along I am. Does anyone else feel like they know?
