First pregnancy, blur mum 🤰😂

Hi mummies! 😊 This is my first pregnancy, and I’m currently 17 weeks pregnant. I’ve noticed that many mums seem to be taking various supplements throughout their pregnancy. My gynae hasn’t mentioned anything apart from folic acid, so that’s the only supplement I’ve been taking so far. Is that normal? Are there any other supplements that are considered essential or recommended during pregnancy? Just wondering what everyone else is taking. Thanks in advance! ❤️
