Dha and prenatal?

Niesel • 25 years old, born and raised in Oklahoma.. mom to a beautiful 3 year old girl and expecting my second daughter via c-section on Sept 14th. 💚✌
Anyone else taking a dha supplement on top of their prenatal? I bought some and have taken it the past few nights but haven't discussed it with my Dr. I'm guessing it's not a big deal? But any advice is appreciated!
