Trouble with my scans

Hello iv just had my 22 week scan and had one at 20 weeks and I'm a bigger girl... And they can't tell me the sex of the baby because it's hard to see on a scan is it worth me getting a 3rd scan with another dr? Or should I get a 3d or 4d scan? It's made me feel a bit shitty cause they say it's hard to see through my "weight" 😢 I'm just going through my local hospital just wondering if any other bigger lady's have had the same issue or is it just the people doing the scan cause they don't seem to care! Even my husband seem too think the lady's doing the scans are quite rude and don't seem too care! Iv had a few of my friends say the same thing about their scans and they are a bit smaller than me!  😭🚺🚹🚼 thanks lady's! 😘😍🚺🚹🚼
