7 week ultrasound

Denise • married to my best friend and mama to a 4 yr old boy 💙 and 2 yr old girl💗 and pregnant with TWINS due in July 💙💙
Such a relief and joy to see the baby today. 7weeks and 1 day. I was so worried about having a missed miscarriage, but baby was there with a heart rate of 143. 1st baby, had a mc in September, have endometriosis and told I have very little chance of conceiving and keeping a pregnancy. Praying for a healthy pregnancy the whole time. This was a transvaginal u/s- what would the Ramzi theory say the gender is? I asked the doctor where the placenta was in the uterus and the answer was "top/middle"
