Pregnant, scared and confused?

I'm very worried for the health of my baby. I went into labour last night, but due to major issues was not sure if it was to early. Thankfully the doc was able to stop it, but was wondering if anyone had ever heard of a story like mine before? On Dec.3/07 I took a positive pregnancy test, to confirm that we were expecting ( concieved about the 10th-12th of November) On Dec. 6 I was hospitalized due to bleeding, and was told I was probably miscarrying. In the three weeks leading up to christmas my HCG levels dropped, but never bottomed out, and on Dec. 24 I had an U/S that they found what was believed to be a cyst in my uterus, but no baby. I was booked for surgery but did not feel comfortable with the doctor so I saught a second opinion in early february, and was told I was once again, preggers. (WOOHOO) I was booked for an ultrasound, and it was confirmed, but they found NO CYST, only one healthy baby, who they dated at about 9 weeks gestation. cont'd in additional info
