Hey girls I just found out I’m pregnant! The problem is I don’t know how many weeks I am since I had a miscarriage last month, I don’t have a doctor so I’m wondering when should i make an appointment? And do I call to the hospital or? Sorry I’m completely new to this also I don’t want to tell nobody yet about the pregnancy until after the appointment
