Just stopped taking birth control a week ago. can i be pregnant? an feeling it so soon?

Possible, not likely: While it is possible it is highly unlikely. Nevertheless you may want to confirm or sent with pregnancy test.

Unlikely: If you had been taking your birth control consistently prior to stopping, it generally takes two weeks to ovulate and another two weeks after that to have a positive pregnancy test. You may be feeling breast tenderness , pelvic fullness or other symptoms associated with ovulation as your body is preparing to do that again.
