HCG levels

Alicia
So my Drs office called me and said my HCG levels were 31,000 Saturday and Tuesday they were 35,000... which I thought was good until he said they should have doubled not just gone up a little 😒 so he is ordering an ultrasound... I went in to the urgent care Saturday after I had pink on my toilet paper but that was it I haven't had anymore after that I haven't had any cramping or pain 
Just mild nausea and sore breast 
According to my lm I should be 8w 5D and I wasn't schedule to see my OB doctor until 20 June that would put me up 11w3d I am just staying positive and leaving it in Gods hands I know everything is Ok with my baby
Anyone else with a Similiar story ???
