10 days of missed periods with slight white discharge, mild headache, and lower back pain, am i pregnant?

Take the test: The over the counter pregnancy test is very accurate. I would pick one up this weekend. Positive or negative - it's better to have some idea rather than getting so worried. I would also recommend making an appointment with your Gynecologist next week. Avoid alcohol and unnecessary medications until you are sure you aren't pregnant. Be sure to be on a multivitamin and drink lots of water.
