I had my ultrasound at what I thought was 12 weeks along adn they told me baby measured 14 weeks and lmp date they gave me May 26 was 2 weeks after my one period May 11 and 2 weeks before my next period June 9 (which was a short period). I had intercourse on May 19th, June 8 and June 22. I am so confused by this still even being this far along pregnant. Drives me nuts. BAby is showing yet 9 more days ahead now via u/s.
