...but how do they actually know baby is still developing on track after your 20 week scan? After 20 weeks I just feel like I've got midwife appointments every few weeks where I'm not there longer than 5 minutes, they check my blood pressure and urine sample and that's it, sometimes listen to baby's heartbeat. Seems like they do stuff to check on me but not actually specifically check on baby. Do they just assume baby is still growing and developing ok as long as there's no reason to suggest otherwise from me? I read posts from people saying baby is measuring ahead etc but they don't seem to actually measure baby at all after the 20 week scan?
