I had my first ultrasound of my first pregnancy on Monday. The gestational sac measured 6 wks 0 days. No yolk sac, fetal pole or heartbeat seen yet. The Dr said not to worry, that it was just early & has me coming back in a week (next Monday). I'm totally panicking & the Dr seems completely unconcerned. He says this happens A LOT & that he's not worried because he pretty sure we should see a heartbeat next week. I'm still nervous though!
