anatomy scan

I'm 20 weeks and 4 days, I had an anatomy scan at 20 weeks exactly. I've been so anxious this whole pregnancy so far especially before a scan - the lady doing the scan wasn't exactly reassuring, if anything she made me worry more. She told me the baby isn't in the right position so she's found it too difficult and I'll have to come back another time. She left bruises on my tummy where she was prodding and poking so much and I just feel more worried now than ever. Like my partner said I know the baby is ok as we saw a heart beat and stuff but she didn't even at least go to the baby's little face quickly for us to see it or anything. Has anybody else had this? It makes me feel so deflated seeing everybody's lovely anatomy scan pics and gender reveals! :(
