Can make u pregnant ? i had in wid my bf on 30 may.. dat was d 2nd day of my periods..?

well all i can tell you is calm down...since i know how you feel, but for somekind of reason when you do anything ual your period changes..or sometimes doesn't come till later or the next month. That happen to me like 3 times,and i knew the sperm didn't enter me, but i was still worried, but i wasn't pregnat in the end. My period would sometimes delay up 1 month or 20 days...but if you are worried, it's better if you tell your mom. I eventually told my mom and she didnt told me anything(im 15 BTW)
