How many times did RE order beta

Le • Tue, May 07

Hi. I got my first and second beta done 15 dp iui 122 and 18 dp iui 421 (doubling time is 1.7d or 40h). My nurse asked I come back for another beta tomorrow. And suddenly I’m getting anxious that something is wrong that she is having me come back. Is something wrong? How many beta tests did your RE had you take? Also when do you get the first ultrasound? Thank you! Leah
