hi im 19 and im engaged with my bf and i was wondering can i get pregnant after having abortion and 2 days after i have an unprotected sex. is there a high risk for me to get pregnant. even though i took home pregnancy test after a month i got an abortion and it said negative? also after that i took the test me and my fiancee had intercourse and the condom fell off and the next day i took emergency contraction pills and i didnt have a side effects. does it mean it works or not.? please respond as soon a possible
