i am 20 y/o. my skipped my period and its kinda long time for me..i think my last is from 2nd week of February and until today my period isn't present.. and by the way thyroid is present. recently i am having oral sex with my boyfriend and he nearly inserted his private part and it remained outside my part. my question is: is it possible that i get pregnant because his sperm touched my outer part of the vagina? and why i am delay? i would appreciate your opinion.. please reply.
