Vitamin D Levels

Cornstarch7

I'm 36w3d. My vitamin D levels have been low since the first trimester. I've been supplementing and they went up, but they have dropped again in the third trimester. They are at 20 and they should be at at least 30. The doctor doesn't want me to increase supplements because I'm already taking 4,000IUs plus the D that's in my prenatal vitamin. I live in the midwest so we're heading into a very bleak season, which usually causes vit D levels to drop even more.


Has anyone had this and ended up with post partum depression as a result? Did it negatively effect breastfeeding?
