Family problems

Went in for an ultrasound Monday but baby being very active but stubborn had legs closed. The doctor said we can try again in 12weeks!! I was so heartbroken they didn't even spend but 2min trying to figure it out or try to make the baby move, So me being very impatient called and today we are paying to go get another ultrasound done to find out. My family is very upset that I won't wait and said that I'm being selfish. My mind has been racing with thought of why they are so upset?
