I had some brown spotting at week 9.. Passed a small amount of tissue. Didn't freak out too much as brown tends to mean old but notified my doctor anyway. He ordered my hcg levels tested. Thursday they were 76000 and Saturday they were 80000... I am currently travelling for work and got a call from my doc saying I need an ultrasound immediately as my numbers weren't doubling. I thought they started to plateau around weeks 8-10. I have an ultrasound scheduled today but cannot help but be nervous. Worried. Etc.
