okay well i am cramping a little bit after my period which it has been over for almost a week now and i am also having headaches and tiredness and sore breasts and my lower back kind of hurts and i have gained a little weight. the most i have done with my boyfriend was oral but his penis never touched my no-no area but what is going on??:( i may have gained weight because i have not worked out in a month and i normaly work out frequenty but i dont know. am i pregnant or what?:(
