Thyroid Hormone (TH) (Triiodothyronine and Thyroxine) hormone produced in the thyroid; increases metabolic rate, raises oxygen consumption, increases heat production, secretes growth hormone, promotes alertness, and grows skin, hair, bones, nails, and teeth. Calcitonin.
If you take a pregnancy test before implantation occurs, the test will tell you that youâre not pregnant (since the production of the hCG hormone has not started, this hormone will not be in your system, and the test will not detect it).
Your body does not produce this hormone until implantation (when the fertilized egg attaches to the uterine wall). Iplantation does not occur until 6-12 days after ovulation. The soonest you can take a pregnancy test and get a positive test result is seven days after ovulation. Even though you can take the test this early, keep in mind that most women will get a false negative at this time. Levels of hCG may not be high enough in your system to register on the test.
