We're Pregnant!!!!! AGAIN with baby #2

i took a pregnancy test october 26 2013 early in the morning not expecting to get a postive the test was really lite i told aaron at dinner that night and he was so happy he started crying i was only 3 weeks and 3 days when i took the test we told grandparents and my sister on october 27 2013 everyone was so excited for us but then it got scary i started to cramping and bleeding Nov 5 2013 i called the doctors and told them they had me get my blood drawn to check my hcg levels well after a couple days i got the results back saying my levels doubled so then that scare was over we set up our fist appointment for Dec 2 2013 to see how far along i really was when Dec 2 came i was 8 1/2 weeks doctor did a ultrasound and told us baby looks to be 2-3 weeks smaller then its supposed to be so then we started to get worried then he turned off the ultrasound screen and said it looks like baby stopped growing at 4 weeks i want you to go get hcg levels done and see where they are if they are going up then we will have you come back in 2 weeks and do another ultrasound dec 4 i got results that my levels were really low meaning i miscarried i was so sad i couldnt breath while i was talking to the doctor on the phone i wiped my tears and put on a brave face for zailey that night i broke down and couldnt stop crying WHY did this happen it kept going in my mind I know things happen for a reason but you truely dont know how it feels until you have gone through it I go in Dec 10th 2013 For a D&C (to remove baby) i am so scared I will let you guys know after its all said and done until next time
