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).
A home pregnancy test can usually detect pregnancy hormone 3-4 days after implantation, but the earlier you do it, the more likely you have to have false negatives if you don't have enough pregnancy hormone in your body to register on the test but are in fact pregnant. You can get false negatives for up to five weeks.
