Hi Doctor, I Just Had My ET Done On 18th

Hi doctor,

I just had my ET done on 18th dec 2015. Had blood test on 3 jan and hcg lvls were 458. Den did anothr blood test on 6th jan and lvls rose to 1500. So right now i am 5w. My U/S doc saw only gestational sac on 7th jan. She said this is completely normal as this is too early and calld again on 19th for anthr scan. I am being positive. I want to ask has the same happened to anyone and still everything went fine. Today i m feeling very lathargic
