Pregnant: Are you asking if you could be pregnant? If you are not using birth control, the answer is, of course. Sore nipples can be a sign of pregnancy, but they don't have to be. Same with nausea, may or may not be pregnant. A home pregnancy test is best way to determine if you're pregnant. If not ready to be a mother, be sure to see family planning clinic or doctor for birth control!
