there is a chance that you might not get preg but there is a huge chance that you can so yah i agree deffently make sure to take a HPT when ur suposed to have ur period, dotn stress though or ur period will come late just try to feel normal, but talk to ur BF about what might happen if u are preg if you want an abortion or keep it but deffently take a home preg test when u are suposed to have ur period.
as long as he came in you there is a likeability that you can get pregnant. you shouldve taken the morning after pill just ot be safe. i think the last day to take the pill is 3 days after exposure but im not sure. take a pregnancy test in a couple of weeks.
