Apart from eating a balanced diet (but avoid raw food or undercooked food), take folic acid and dydrogesterone which can be prescribed by ur doctor. :)
Doctor put me on dydrogesterone. It’s a hormone pill that helped to stabilise my pregnancy. Maybe you can speak to your gynae about this.
folic acid i guess? maybe calcium, multivits & fish oil when u enter 2nd tri and beyond
Avoid caffeine, high mercury fish and raw food.
