it is not likely. during an abortion they scraped everything from the vagina so any semen still there would have been removed and she would not have ovulated at that time because her body still thought it was pregnant. best thing for her to do is see her doctor.
my girlfriend was pregnant and chose to have an abortion 3 weeks later a pregnancy test reads positive. she said she still feels pregnant so she took the test which was quickly positive. we had unprotected sex before the procedure and then with a condom a week ago. after sex with the condom she started bleeding again and she said it was right before we had sex that she started feeling pregnant again. . i'm wondering if any sperm that might have ended up in her before the procedure would have survived and gotten her pregnant again or if there were some other concerns about after the procedure.
