I m 18 years old, and I think I may be pregnant? I ve taken a home pregnancy test and it came out negitive, but my body is telling me otherwise. My breasts are bigger, I m urinating a lot more than usual, my craving for tabacco has pretty much gone away, I get drunk on one drink all of a sudden , I m nauseas , my tummy has a constant grummbling feeling even if I ve eaten? I m very confused because the test says negitive but my body is telling me something else, please help?
