Someone told me that if you pee in a cup and then put a birth control pill in the cup and use that for a pregnancy test that it will come back positive because birth control has HCG in it, is this true?

"The combined oral contraceptive pill, often referred to as "the Pill", is a combination of an estrogen and a progestin, taken by mouth to inhibit normal fertility."
http://en.wikipedia.org/wiki/Birth_control_pill

"Human chorionic gonadotropin (hCG) is a peptide hormone produced in pregnancy, that is made by the embryo soon after conception and later by the syncytiotrophoblast (part of the placenta). Its role is to prevent the disintegration of the corpus luteum of the ovary and thereby maintain progesterone production that is critical for a pregnancy in humans"

"Pregnancy tests measure the levels of hCG in the blood or urine to indicate the presence or absence of an implanted embryo. In particular, most pregnancy tests employ an antibody that is specific to the β-subunit of hCG (βhCG). This is important so that tests do not make false positives by confusing hCG with LH and FSH. (The latter two are always present at varying levels in the body, while hCG levels are negligible except during pregnancy.) "

"Will taking birth control pills make a pregnancy test inaccurate?
No. Pregnancy tests are NOT interfered with by the hormones of oral contraceptives. You are correct that estrogens are elevated in pregnancy and birth control pills contain estrogens, but that is not the hormone that is measured to determine pregnancy. All pregnancy tests measure the beta subunit of a placental hormone called human chorionic gonadotropin (HCG). You will often see it abbreviated as beta HCG. It can be measured in the urine or blood. While it depends upon the sensitivity of the specific test, most home urine pregnancy tests (sensitive to 25 mIU) will turn positive about 13-16 days after conception. If you were not on oral contraceptives, this would mean about the time of the first missed menses. When you are on oral contraceptives, ovulation could have occurred at more irregular times so that all you can say is if the pregnancy test is negative, you are either not pregnant or are less than about 14 days pregnant from ovulation.

No. Birth control does not contain the pregnancy hormone.

No birth control at all has the pregnancy hormone in it.
