I'm 13 weeks pregnant and have had a NIPT blood test (waiting for results). I now need to decide whether to have the first-trimester screening ultrasound as well (I live in Germany so the blood test is offered free at your gynaecologist but you have to book privately for the screening ultrasound).
Are there any advantages / disadvantages to only having the blood test and not the ultrasound as well? Is it best to do both?
Any advice would be really welcome!
