I had an iui on sept 1st. Got my first beta results on sept 15-246, sept 17-716, sept 19-2305!! We went fir our 1st ultrasound on sept 21st and saw the sac at 4 wks 5 days. I went back to my RE yesterday to check my betas again, he called me back to say that they stayed around the same number as last wed (around 4,000). Am I in the process of miscarrying again? I haven't had any bleeding, but is it inevitable....
