It takes approximately 48 to 72 hours for your level of hCG to double its levels. What this means for you depends on your body. If your level of hCG prior to pregnancy is 2 miU, it might take two to three days for it to double to 4 mIU and another two to three days for that to double to 8 mIU. This means it could take a week for the most sensitive pregnancy test to determine whether or not you a pregnant.
