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).
If you think youâve experienced implantation bleeding, the advice is that you need to wait at least 3 days before taking a home test. Before that, thereâs unlikely to be enough of the pregnancy hormone hCG to give a positive result. If you can bear to wait 5 days, thereâs even more chance it will be accurate.
