I have my 20 week scan this week all previous scans I have had - private and nhs have shown a healthy baby. I had a MMC last year and found out via a private scan very early on. I just can’t seem to relax and keep thinking the worst. I’m worried they are going to tell me bad news even though I’ve had no signs to show something is wrong. Everyone tells me not to worry - easier said then done, I just feel like they don’t understand. What should I expect at the 20 week scan in terms of what they are checking? I was hoping it would get easier the further on I get but Im constantly anxious and expecting the worst after last time, don’t want to get too excited but really want to try to relax and enjoy it. It’s just so difficult
