Prenatal care. It is important to schedule your first Obgyn visit to start your prenatal care. Your doctor can guide you through this journey. Typically an exam and sonogram is done to confirm a live intrauterine pregnancy. The lack of negative pregnancy symptoms can not be used to draw conclusions on the status of the pregnancy.
Probably not. The lack of symptoms may mean you are just lucky! It doesn't necessarily mean anything is wrong. Best wishes!
