Scared

Ok so this is whats going on i went to a doctors appointment and the doctor told me that since i had my son vaginally and he got stuck by his shoulders because he was so big she wanted to do an ultrasound on this baby (my second baby) to see how big she was and to see if i needed a c-section because they didnt want the same thing happening again that when it happens once (that the baby gets stuck) your at a higher risk for it to happen again.. soo i wanted to know if anyone had the same experience and what did you do I really dont want a c-section specially having a toddler that has so much energy i cant do it
