hi my boyfriend and i have sex freqently we use condoms everytime but the last time the condom we used was a bit snug,my boyfriend is quit large he says he didnt see anything wrong with the condom no tears holes ,bubbles air nothing like that but i havent gotten a period yet and he suggested that maybe his size could have thrown off my cycle becuase he is the biggest ive been with but its been 5 days from when i usually start my period and ive had tenderness in my breast mostly around the nipple and a white creamy disscharge from my vagina and im wondering am i or could i be pregnant ?
