I am 22 yrs old woman... and I just did abortion and today I tested after 10 days... so result is positive... is it possible that the test shows wrong restult?

How did you do abortion, at a hospital or clinic ?
What type of test did you use ?

You can not test so soon after abortion for any valid results

A pregnancy test measures the amount of hormones in your body. It is probable, that those hormones have not dissipated yet causing the positive result.
