So me and my boyfriend had unprotected sex Wednesday morning and he put it halfway inside me only for about 10-20 sec cause it hurt so bad. He didn't ejaculate at all and when I jerked him off it took about 30 minutes for him to ejaculate (he didn't ejaculate near me or on me) after that we didn't do anything else cause I was too scared of getting pregnant. For a few days I've been really gassy and just gassy and when I eat I still feel hungry after. Does this mean I'm pregnant??! Please help. I'm only 17 I have my whole life ahead of me I don't need a child rn ):
