Rainbow is 12 weeks today with pics!

Baby was being very stubborn and wouldn't hold still long enough to get very good pictures, we finally got a good view of the heart rate which was 184! I did get to see some kicks and we are supposed to be 12 weeks but we are measuring 2 days behind which is consistent with my 8 week ultrasound so our little Rainbow is right on track. I included some pics, I can't really tell exactly what I'm looking at but maybe someone else can. Any guesses on gender? My first child was a girl and heart rate was 187, as I said this one was 184 today 😁.
