Okay so me and my boyfriend were doing some heavy petting through my underwear but i'm not sure if his precum from me touching him got on his fingers. I got my period two weeks after.. So does this mean i'm not pregnant? I know im a virgin but that doesn't mean anything. It's been 3 weeks I feel really naucious all day and having pain around my navel... Is that a sign of pregnancy? Or no. Because a lot of people say 'morning sickness' takes place 6 to 12 weeks after conception. And that you can't feel a babys heart beat until your near second trimester.. Am I just being paranoid?
