Worried mummy

I just don't know what to do 😭😭 I'm nearly 21 weeks pregnant and had my 20 week scan on Monday. It showed my baby has a twisted foot. All I can do now is worry until my next scan on Monday. But I keep thinking the worst like what if my baby isn't growing any more. Or what if my baby has to have its foot amuputated. I know I shouldn't worry just yet. But there's nothing else I can do. I keep crying and I just feel so sick. 😭😭
