ultrasound 6 weeks 4 days - ramzi guesses?

Ho
Everything looked good, saw the heartbeat! Doctor said my gestational sac is a little elonglated and perhaps not as round as normal but she wasn't worried, just to note. 
I was right on the money of the due date by tracking my ovulation, despite my last period being in March. Jan 14, 2018 confirmed! This was a quick transvaginal scan to confirm due date. 
Two weeks til I get my first "real" intake so that will be around 8 weeks 5 days next time. 
Ramzi guesses? Not putting too much stock in that but interesting none the less. :)
