Im almost 17, And i cant stop thinking about being pregnant... I know this is odd, and im not crazy, its just, okay, Im faithful with my birth control pills, and me and my boyfriend do have sex alot, and im just courious on how im not pregnant? the pills arent 100% it just doesnt make sense, so im worried i may not be fertile, or even him... And this is scary becasue weve been together for 3 years, and we plan to stay together, i do plan on having kids with him... it just worries me... and i cant really go to the doctor, becaus eim to young, i know that, but i have no idea how i cant be? and worrying about that has even wanted me to get pregant, then when i think about it i come back to reality, and know i cant, im not even out of hs yet... does anyone have any advice? to help calm my nerves?
