Can birth control cause a negative reading on a home pregnancy test and on a blood test?

not usually, just going to check my lone remaining test to make sure though.
okay, I just checked the instructions and for the one I have it says that the test should not be affected by alcohol, antibiotics, fertility drugs or contraceptive pills. Now that doesn't mean that it will not be affected or that it will, just that it is designed not to be. If you are taking birth control chances are that you aren't pregnant, if you aren't taking them anymore and got a negative result you mught just be late from stress possibly. A blood test is generally fool proof as home tests can give you a false positive or a false negative test for a couple different reasons.
If you are still concerned talk with your doctor, there may be something else going on, or you are just not pregnant this time.

No. Birth control pills are typically estrogen, progesterone, or both. Pregnancy tests, either urine or blood tests, test for the presence of HCG (human chorionic gonadatropin) which is the hormone produced to support early pregnancy.

Nope. Home pregnancy tests look for the presence or absence of HCG (human chorionic gonadotropin?). The synthetic estrogen or progesterone in birth control pills won't affect them at all.
