Hcg levels and doubling time

Elizabeth

Hey everyone! I have had 3 beta hcg draws and don't know if I should be cautiously optimistic or preparing for the worst...the first two were not even close to the 48-72 hour doubling time but the second and third were decent. I have another draw tomorrow. Anyone with experience or knowledge?

4w1d: 75

4w4w: 118

4w6d: 219

Update: draw for 5w1d was 453. My doctor wants to just wait until 7 weeks for an ultrasound since they are now "doubling as expected". What do we think about this?!
