breech baby

Tosha

so I had my 21 week 6 day ultrasound today and found out that my baby is in breech with legs and arms up by her face I'm really worried a scared this is my 5th baby but my 4 boy's I didnt have this problem with them. I will be 6 months as of tomorrow and just dont know how to handle it due to the fact she is only 1lb 1oz with my boys they weight more at this time of the pregnancy please help calm my nerves someone anyone.
