Congrats! Not much tbh. You can start with folic acid first, I got mine from Watsons, Blackmores. Just the one with only folic acid will do. Your gynae will prescribe during your visits, so don't have to buy too much, 1 small bottle will probably be sufficient till your appointment.
rest well, don't lift any heavy weights, avoid stairs, take folic acid. ask Ur husband to do all the work. That is how my wife did it 😂
congrats. the only important thing now is to start taking folic acid.
