I had a MC at 6wks on the 8th March, today I've been told I'm miscarrying again at approx 6 wks. I didn't have a period inbetween the two pregnancies...I'm going crazy, why did I fall pregnant again so quickly, I didn't even know it was possible without having a period inbetween...all those horrible emotions all over again just when I'd got over them. I feel sick. Please can someone explain what a chemical pregnancy is?
