Cracked corners of lips

Eve

Hey everyone! Don’t know if you'd know or not but the edges of my mouth are really cracked and a woman in Holland and Barrett said I'm deficient in either Vitamin B or D. I'm taking pregnacare supplements every day but I bought extra iron and Vitamin B tables. Do you think it's safe to take them on top of my pregnacare? Sorry for boring question!

Any midwives our there?
