Hello! The doctor saw me and prescribed a referral to the maternity ward. I asked when to go, and she said whenever you want, even today. It's like waiting for the birth in the hospital. I don't understand why I should stay there if nothing bothers me, and I can wait for the birth at home. What is the best time to go for an examination? There's still time until the due date, which is July 30th.
