Vit D Deficiency & TTC

A couple days ago, I got results from the labwork I requested to be done due to numerous health things. It came back showing my Vit D level at 5! I was shocked. Then I learned about the symptoms and many of them ring true!! Having low Vit D can cause infertility! I am now on calcium and Vit D supplements. Anyone else experience this? Any luck conceiving after levels were higher?
