So I'm supposedly 7 weeks along and my doctor ordered another HCG test yesterday after complaining on sharp lower back pain. I've been in and out of the doctor's office doing blood testing for 3 weeks now. My levels are in the 1900's but my doctor seems to be really happy with that? I keep seeing everywhere that most mothers have levels in the thousands (5,000-20,000) by this time. Is this weird? Has anyone else had this happen to them?
