Girls, I'll probably ask a stupid question... I stand in a polyclinic that is attached to the maternity hospital (right in the same building they are). I stand with my registration. Question: will I give birth in the same polyclinic where I was observed? (The maternity hospital and polyclinic are satisfactory) or do I need to sign some kind of contracts or certificates? (I will give birth for free). In general, tell me what and how it's done.
