Help. I have gone through 2 mc and have dd1 after 3 pregnancies. I am now about 8 weeks through preg4 and spending most of my time panicking about every little symptom. How are you supposed to relax when the body has previously played such tricks. I am convinced that I am about to miscarry again despite seeing the heartbeat on a scan. I am quite definite on the dates of my LMP but the scan dated it a week later than I thought. Does this mean it is not growing as it should?
