is it possible to miscarry and not know?

breanna

i’m 9weeks 1 day pregnant. when i initially found out i was pregnant, my doctor told me the only red flags during pregnancy were severe pain and heavy bleeding. these are obviously signs of a miscarriage. but i was watching Marley & Me, have you guys seen it? there’s this seen where Jennifer Aniston’s character goes in for her 10 week appointment and the doctor tells her there is no heartbeat. so she miscarried, with no symptoms, no pain, and had no idea? is this possible? how common is this? this makes me so nervous. i have had an easy pregnancy with little to no symptoms, and the thought of miscarrying without having a clue has me scared to death.
