help!

im freaking out! i had sex back in april and had my period every month-except june. all the periods i passed largeish clots. i took a test in may and june-i would have been nearish 10 weeks. both tests came negative. i know i'm most likely not pregnant but recently i have been experiencing weird cramps and odd feelings in my stomach. ive been having creamy white discharge the whole 4 months and ive had it like that before this whole scare. last night i had a dream i was pregnant and i know sometimes people who have those types of dreams end up being pregnant. i dont have the access to a doctor or a pregnancy test(im still young and my mom would do and i dont feel comfortable telling her). do you guys think im pregnant or just crazy?
