test becomes negative after three to four weeks following termination of a pregnancy. A perfectly done abortion has no bleeding following the procedure. Bleeding following an abortion usually signifies an incomplete abortion
or an infection. With an incomplete abortion, pregnancy test will remain positive.
What you should do is to do an ultrasound
to check for retained products of conception and for indication of a probable uterine curettage.
Best regards and hope this helps you.
