Metallic smell?

Ok so TMI and a bit embarrassing. We have been TTC and my OB has me start taking prenatals as she said the vitamins and everything would be good to support getting pregnant. Ever since I started taking them I have this Metallicy smell when I pee. Is this normal? I have an OB check up in 2 weeks and I will bring it up then but I wasn’t sure if anyone has experienced this before. Thanks in advanced. ❤️ baby dust for all you TTC mommas!!
