Any pills to avoid?

Hi mommies! I'm a first-time mummy, just tested 2-3 weeks pregnant using ClearBlue yesterday. I'm currently on Blackmores' folic acid pills and Purest Co. collagen, would it still be safe to consume those during pregnancy? (So anxious because I'm so new to this! 😅) Nausea, stomach cramps and diarrhoea got diagnosed as stomach flu by the GP two days ago, so he gave me some probiotics. Safe to consume those too?
