Is vitamin d supplement recommended for pregnant women with a level of 22? will low vit d affect baby/pregnancy? safe to take with prenatals?

Very important : Vitamin D3 is a critical hormone and plays an important role in fetal development. An optimal level is 50ng/dl so you need to supplement. Work with your doctor to put a plan in place.
