Already confirmed BFP, but.....?

I would say you are wasting your time and money by doing so. When the doctors took blood from me to check my levels they was at 45 they said something could be wrong or they just caught me in very early pregnancy so they had me come back for another blood test and my levels had gone up quit a bit. Your levels should double every 72 hours i think is what my doctor told me i could be wrong though. Try to relax.
