Only about a week in of possible pregnancy, dark tender nipples, peeing a lot, could i get these symptoms so quickly? could i be pregnant? been trying

Not too likely: Usually you do not get symptoms of pregnancy so early. Occasionally you will have some light bleeding that you think is a period but really you are already pregnant. If that happens then you can be having symptoms if you are a month farther along than you think. If your pregnancy test is positive please take a prenatal vitamin daily and see your doctor.
