I had my 8 week ultrasound after having 2 miscarriages, we got a heartbeat and baby was measuring right on track doctor says. He said he would see me back again in 4 weeks 😲😲😲😲😲 4 weeks!!!! 1 week is done, but still got 3 more to go.. how do you get through that? How do you know baby is okay In those 4 weeks?! This is so dreadful!
