I would honestly say that if you were using birth control and condoms, that pregnancy is pretty unlikely. Birth control pills can cause moodiness in some women, so can pms... Technically your body is still getting used to the pill, so there is an adjustment time. You can take a test if you feel like it would make you feel better :)

...I wouldn't stress over it...You probably don't have a chance at all of being pregnant....Just take a test ...Or go to the doctor ...It'll make you feel better...Your probably just stressed ...Or your body going through a change in life maybe....
