Ive never had intercourse befor and at least two weeks ago around march 15th area. me and my boyfriend were playing around. and he started fingering me and then . and swallowd and i know u cant get pregnant from swallowing. and when i got finished i got up and washed my hands or at least i think i at least whiped them off on a wet wash cloth and he went to the bathroom and washed his hands. then the same day we were messing around again and he started fingering me again and then i and i went to the bathroom and eiether washed my hands or at least whiped them off with the same wash colth. then when he left later that night i we had phone sex and i played with myself not fingering just rubbing. now its march 28 and and i still havent had my period. i told my mom i havent had my period and she asked have i had sex and am i pregnant and i said no i havent ever. and she was like young girls can have unregular periods and might miss a few. im so scared idk what to think or do. :/ please give advice.. should i go to the doctor or what? give advice please
