You're definitely not pregnant unless semen came into contact with your vagina, and by what you describe this did not happen.
i feel the same way except i did not have sex me and my bf was just fooling around i had on my clothes but he didnt an im so so scared sigh
recently ive been having little pains around the opposite side of the bladder. any clue?
god thank you u make me feel more clamer (if thats a word)
If you only had sex the 17th, what you feel now is NOT due to pregnancy. Symptoms don't just start overnight. You have to first be ovulating (which doesn't happen on a females period in 99% of women) and then the sperm and egg have to meet. Once this happens it takes anywhere from 7-14 days for implantation to occur. Only once implantation occurs do you feel anything due to pregnancy.
Many girls when worried about pregnancy start to pay more attention to their bodies. Humans in general get headaches and tried. Maybe you're sick. Nausea, fatigue and headaches are also symptoms of a flu. It's best to not look into every symptom you feel. They really don't mean much in determining pregnancy.
o and now its the 19th and im getting really bad headaches and getting tired alot. recently i almost threw up.
Depends on when you ovulate, if you ovulate early, then yes it could be possible since sperm can live up to 5-7 days in perfect conditions in there. All you can do now is wait 2-3 weeks or when your next period is due and if it's late then take a test.
