I had an abortion 6 weeks ago, i had blood work done 5th wk 6th day since the abortion, my tests came back indeterminate. could i still be pregnant?

Possible not likely: The pregnancy chemical that gives a positive test falls slowly after an abortion. With a viable prenancy it doubles roughly every 2 days. If the value was positive before the abortion it should be higher now if a normal pregnancy was continuing. It is more likely that it simply hasn't dropped completely yet.

Please check again: This should not be pregnancy as you just had an abortion. If you suspect, please check in 1-2 weeks again.
