Have your doctor perform a blood test to give you a definite answer as to if you are pregnant or not.

A pregnancy test can only give you "a negative result" (probably not pregnant) or "a positive result" which indicates the likelihood of pregnancy.

Is 15 days after possible conception too early to get an accurate result from a pregnancy test?

No, some pregnancy tests say they can give you an accurate result 5 days before your missed period. If you get a negative result, it is best to test again a couple days following your missed period to ensure you are in fact not pregnant. If you get a positive more than likely you are pregnant as it is more likely to get a false negative than a false positive. If you do get a faint positive and are still unsure, take another test a couple days following your missed period and if that test is positive call your doctors office and make an appointment. Good luck!

Will a false pregnancy pseudocyesis give a positive test result on a home pregnancy test?

Although I do not have a uterius, flopian tubes, or a vagina i still know that if a home pregnancy test is negative that the result is not completely accurate. My professional advice would be to take home 5 pregnancy test that you would get in your everyday grocery store and whether it be positive or negative when they're is 5 tests it doubles the accuratacy. If 3 out of the 5 say you are pregnant than most likely you will be expecting. If 3 out of the 5 say you are not pregnant than most likely you are not, but home pregnancy tests are man made and have errors, so i would still see your doctor to confirm the home pregnancy test.
