Sure it isn't 4500?: because 45000 would be the highest dose I've ever seen. http://americanpregnancy.org/pregnancy-health/vitamin-d-and-pregnancy/ and the 4500 is standard as you can see. Furthermore, while there is an association between complications and low vita d, since Most PRegnant women have vita d deficiency, the risk can't be that bad.

See answer: Both hypothyroidism and low Vitamin D can affect both pregnancy and the developing fetus. Thyroid hormones are crucial to fetal brain and nervous system development, especially during the first trimester. Vit D likely more crucial during the last trimester for adequate bone and skeletal growth. If well controlled and monitored, women with these problems can have healthy, unaffected babies.

No: It should not affect your baby but make sure your level is not too high. It can be stored in your body, Vit D that is, and so have level checked! Make sure thyroid dose is okay too. Needs change ( usually go up with pregnancy) and that is important for baby's neuronal development.
