I found out at 1.5 weeks after conception that I was pregnant just by chance. The first blood test at 1 1/2 weeks came back at 19 and the second one 2 days later at 21. At 2 1/2 weeks pregnant my results only went up to 27 which is within the 0-50 range for the time of pregnancy.
Question is, given it is so so early is it still a normal range if it hasn't been doubling so early on? or could it be just because we tested so early?
