Not knowing is driving me mad! She is 2 weeks late on her period with sore breasts and other symptoms of pregnancy (bloated, fatigue, frequent urination, etc). She has taken 4 pregnancy tests and 2 have came out with a very faint positive line. The other 2 have been negative. She still hasn't started her period. Also she's having bizarre mood swings. What should our next step be? Do you think she is pregnant?
