On the 2nd week of august, me and my boyfriend did dry humping without clothes. Then he tried to insert the tip of his penis but he immediately removed it. He didn't cm. I have an irregular period but until now i didn't get my period. My boobs are now hurting for almost one week and i am experiencing lower abdominal cramps sometimes. I am so paranoid that maybe i am pregnant. And also, i used pregnancy test on the first week of September and it was negative but i used my afternoon urine. Do you think I'm pregnant?
