Hey my name is nichole I recently went to the doctor on August 25 and I took a blood test for pregnancy. My hcg level came back a 10. How far along am I

What was the first day of your last period?

July 12

Even at best there is no way to know the exact date, or even the exact week, It is always a estimate. So unless you had sex with two or more men around the same time it really does not matter and the doctor as you get further along will give you a estimated due date to plan around

If you are indeed pregnant, you would only be 7 weeks along at this point.
