First ultrasound almost gave my bf a heart attack!

So I’m a twin and I’ve been joking with my bf that we are having twins. Went to our ultrasound today and found 2 yolk sacs but 1 baby so they said I had a vanishing twin. Hopefully next time we will get them! I cried when i saw the baby for the first time. Heart rate was 163! I’m so relieved and happy that everything is healthy
