My beta level of pregnancy is 314 what that mean! ?

Low: Could be an early pregnancy. You should have the test repeated in 48 hr and it should double if things are going well. An ultrasound won't show a pregnancy in your uterus until the level is about 6000.

You are pregnant: BHCG levels are typically used to monitor the progress of and early pregnancy, either good or bad. In normal pregnancy, the level should rise at least 50% every 48 hours. Conversely, in an abnormal pregnancy the value will not rise appropriately or fall.Your value of 314 confirms you are pregnant but a second value/ test would be helpful if your doctor feels it is indicated based on your situation
