Doc Visit update, waiting for 1st scan @6wk

Hi ladies... Need some positive encouragement. So my doc called my hubby today for an appt with my beta reports. While she is happy that the nos are increasing, she is still concerned that it started off low. My 4 beta results were - 34, 85, 230 & 509. I am now approx 4w 5days pregnant (as per this app). Now she is saying we will wait for the 1st scan which is on 19th feb (couple of weeks away) and there should be a heart beat so we know that all is well... I am so anxious and just wondering how I will get thru this 2week wait.

Any positive stories will really help.
