If it's only been like a week since you had sex, trust me you would not be feeling the symptoms yet. The earliest they start to show up is around a month later you could possibly start to getting headaches, and nausea/morning sickness doesn't come until at least 4-6 weeks either...The feelings you are having right now are just from the stress and worry wondering if you could possibly be pregnant. As far is times when you are most likely to get pregnant, the time you have the least chance is from days 17-25 after the start of your period from what I have learned. Chances are you are ok if he didn't climax inside of you, but you can never say never, you do know that the small droplets that come out before the guy climaxes all contain sperm as well, which is why pulling out isn't the safest method of birth control (about 25% effective). You should just go ahead and take a pregnancy test to know for sure (first response is a good one or you can go to the dr and have them do it) so you wont continue to have to stress over this for the next month. Next time I would recommend using something more to protect yourself if you want to be safe. Good luck!

Is it too soon to take a test now since I just got done having my period?
