Open Question: I’m not sure if I’m pregnant..?

Anti-acid is a sign of pregnancy? Or it is only during pregnancy happen? In addition, you really can be pregnant, even if your time? I think this is not a sign of pregnancy. Well, I do not want pregnant, I do not like it, I think I. The only signs that I was a late start and anti-acid. Although I have a very, very not normal times. I was too afraid to take the test .. Does anyone think that these symptoms, I can pregnant ..?
