Well, there was another trip to the doctor today.
My hCG levels from Friday/Saturday were compared with the blood the took Monday. Levels are doubling as they're supposed to.
Got another ultrasound today to see what they could see. I was given the regular ultrasound first to get measurements of the baby and my ovaries. All are healthy!
Next, I got a transvaginal ultrasound to get better pictures of my cervix and the placenta.
I have to call the doctor tomorrow to see what our next step is. Baby looks healthy though, so I just need to rest and relax. No lifting. No stenuous activity.
