We just went in for our 6 week ultrasound and found out we are having identical twins! We knew fraternal twins were a possibility because we did an FET with 2 embryos, but apparently one of them decided to split :) Saw both heartbeats but couldn't measure their rate. Due October 6th, but anticipating a few weeks before. So excited! Finally feel like it's real now that I saw their little hearts going strong :)
