I just had my first very faint positive pregnancy test yesterday and since I have had a previous miscarriage my obgyn has allowed me to go ahead an have my hcg levels and progesterone levels checked. I am currently 10 dpo (yes I know I am early) any how, my results are that my HCG is 18 and my progesterone levels is greater than 40. I will have a repeat blood test on Wednesday to see if they have doubled. I guess my question is, is this normal in early pregnancy or should I be concerned?
