Neither estrogen or progesterone impact pregnancy tests. Taking a pregnancy test at the wrong time can absolutely cause a false negative. While many tests claim they can reveal a pregnancy before a missed period, this is not the case for all women.
When should I take a pregnancy test when on progesterone?
You should continue to take the progesterone until your pregnancy test, which is done two weeks after ovulation. Progesterone can delay your period, so a pregnancy test must be performed. If pregnancy occurs, the medications will continue until around the 10th week of pregnancy.

Can progesterone pill affect hCG levels?
Most birth control pills contain either a combination of estrogen and progestin or only progestin. These hormones keep you from getting pregnant by preventing the ovaries from releasing eggs and/or keeping the sperm from fertilizing an egg. Estrogen and progestin will not affect hCG, however.
What hormone causes a positive pregnancy test?
Pregnancy tests check your pee or blood for a hormone called human chorionic gonadotropin (hCG). Your body makes this hormone after a fertilized egg attaches to the wall of your uterus. This usually happens about 6 days after fertilization. Levels of hCG rise quickly, doubling every 2 to 3 days.
