Ultrasound today! Measuring ahead! Question!
So my LMP was may 20. I ovulated on day 11, proven both by an OPK test plus a BBT temp spike the next day. According to my calculations I'm 12.5 weeks. Tech did numerous measurements and says I'm 14 weeks. How can that be?
I'm doing the IPS testing (u/s and blood work) and I'm concerned about how this will effect my results?
