I am about 6 weeks pregnant. just had a blood test this saturday and found out that my beta count not doubling. It was doubling till last tuesday the count was 1533. but when we repeated the test after 4 days on saturday it was only 2080. Progestrone is rising, its 19. it was 14.5 on my first test and then i took progestrone supplement. I am so much worried now. I had a miscarriage in last February 07 for the same case- beta count not doubling.. but at the time, it was rising very slowly it got upto 1200 only and then i miscarried. But we saw heartbeat for that!! dont know whats wrong with me....anyone have gone through this? anybody know whats the reason for this beta count not doubling? I have an ultra sound and blood test scheduled for thursday... Please pray for me.
