Juliet

Hey guys I'm Absolutely terrified! I went in for my first ultrasound scan last week thinking I was about 7 weeks pregnant and this is all we could see! Two sacs one of which looks emty but the other one she said it looked like an early pregnancy or a non developing baby and I should be prepared to miscary. I haven't had any bleeding or pains but I was absolutely heartbroken to hear this. I cried my eyes out all day! This is my first pregnancy and I am so scared! We've been scheduled for another scan next saturday which will make it two weeks after the first one. Please let me know if any of you guys has ever been through anything like this am so worried!
