I found out that I was pregnant on Feb.5 2006, when I went back to the dr. on Feb 21 for my first ultra sound the ultra sound measured that I was 4 weeks 2 day pregnant, but the doctor thought I was 6 weeks based on my last period. I went and did a blood test for HCG and it came back at 887 with supports the ultra sound, now I went back 48 hrs later and the numbers went up to the 1100's. Now the dr wants me to go back in 4 days to see how much higher the numbers will go up. what is your thoughts on this? I have no cramping and no spotting, should I be worried?
