So my boyfriend and i had intercourse the other day, and as soon as he went all the way in, I got this very painful sensation as soon as he hit my cervix (i think). The pain was intense and sharp, ranging from my uterus up to the spot above my belly button. Now, the pain is only in my stomach, when i press down on it. I'm not sure what's happening. Is this a sign of pregnancy? I am 16, 118 pounds, and a little less than five feet tall.
