In brief: Yes

The b vitamins are safe in pregnancy.
They are in prenatal vitamins and you may not need more. If you take a lot of b vitamins, you may have some discoloration (yellow or orange) of your urine.

In brief: No

Niacin (vitamin b3) is classified with a "c" rating for pregnancy (a being the safest) because there has been fetal harm in animal studies.
There is insufficient data in humans but you should avoid supplementation. You should be taking prenatal vitamins which contain a safe amount of Niacin and plenty of folic acid.
