Ive been sick with mono and strep since December and am just about over it. My boyfriend and I had been fooling around but we didn t have intercourse. He did finger me but I m unsure if there was semen on his hand. I was supposed to get my period on the 31 of January but it never came. Now, i m five days late, but I am having horrible cramps, stomach pain and fatigue. My breasts seem larger than usual with the nipples seeming to be darker than usual. Am I pregnant? That s my main concern. I had been living with four girls, then switched to living with another girl. Did the switch possibly change anything?
