Hcg levels

My levels were ar 208 at 4 weeks which made me super nervous. Went back for second round of blood work and numbers went up to 2236. Seems like I'm on track now for 5 weeks and the numbers are doubling every 48 to 72 hours as they are supposed to be. Still no nausea or vomiting which scares me a but but some frequent urination, cramping and backaches. Hoping all goes well and I have a healthy baby in june!
