First ultrasound

LJ • Baby girl born Feb 19, 2015 and second girl born Jan 20, 2017. Baby #3 due in October!
Due date according to the ultrasound is Jan 31st but my doctor is going with Jan 26th based off of LMP. Heart rate of 135 to 150 depending on when she measured. Any Ramzi guesses as to what gender?  Vaginal ultrasound and at 7 weeks 0 days according to measurements.
