u have to wait till a good month before u take a pregnancy test, because if u take it too early it will be negative. Honey I have pregnancy scares all the time. Anything that my body does i relate it to pregnancy, yes being tired and moody is a sign of pregnancy yes, feeling nausous is. However, you have to think, when did u have sex, did the condom break? what are you biological chances of getting pregnant? Wait awhile, and take the test again. If you aren't pregnant go on the pill.
