I had an abortion 4 weeks ago. My husband and I have had protected sex since using condoms. I have begun feeling nauseated again just like before and took a pregnancy test. The test has come back positive. I am not sure if I am pregnant, or if the hormone is still being detected. My post exam was an ultrasound 2 weeks ago and showed the abortion to be a success, however the nurse said i still had a lot of clotting to pass which has happened since. If I wait 2 more weeks and take another pregnancy test, will the results be more accurate? Or what should I do to find out as soon as possible whether or not I have conceived again?
