I had my first appt this week, I'm around 5 1/2 weeks. Had an internal ultra sound, only saw gestational sac and yolk. Dr wanted to do blood test since baby wasn't visible yet. First one was later in the afternoon, levels came back at 9,105 second one was two days later early in the morning (so not quite 48 hrs) levels came back at 15,778. Nurse said they should double, or almost double. Do these numbers look promising? TIA
