I'm 14 weeks today 🙌🏻 We had the Harmony genetic test the day before yesterday and the technician said the placenta is on the left hand side. This was not a transvaginal ultra sound. At 8 weeks heart rate was 160 bpm, 10+4 weeks 176 bpm and the other day at 13+4 weeks heart rate was 152 bpm. Any guesses? 
8 week transvaginal ultrasound
