No "motherly intuition" on gender?!

Sarah
We find out next week what we are having. From the start I just assumed it was girl because I've always pictured myself with girls.  After our first ultrasound I felt like it could be a boy.  I'm voting girl because my husband says boy. The heart rate has been higher than 140. The last visit it was 157 at 15 weeks.  I hate that I'm not confident with my answer haha!  No matter the gender I will be absolutely thrilled. And maybe that's why k am not sure! Anyone else feel like they didn't know what it was? 
This ultrasound was done at 11 weeks 6 days.
