I am on birth control, but have been having pregnancy symptoms (I have one baby already). If I take a hpt, what are the chances of getting a false reading? I'm afraid to stop taking the birth control if I am not pregnant, yet I want to stop taking them if I am. I hate to wait until my next period (3 weeks away), but don't want to reassure myself with a possibly false reading. I took one hpt, but it was an expired test. Since I have been having these symptoms I wonder if an expired test may have given a false result. Obviously I want to find out as soon as possible if I am, to start preparing.
