due date changed

I went for a dating ultrasound yesterday just to be sure and they changed it. I was due June 29 (thought I was 10 + 5 days.) due date now July 5 and I am 9 +4 weeks, as of yesterday. she said baby looked good. I got to see it moving legs all around. very cool. so in love already. Heart rate was 169. I know it is really early but any gender guesses? (just guess cause I don't think I can do nub or skull theory because of the angle.) thanks in advance!
