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).
Then allow 14 days for the embryo to implant and develop enough hCG to show up on a pregnancy test (96% of pregnant women will test positive by then.) Note: some HPT's say test 5 days before your period is due! or some such thing.Please note they are assuming a textbook 28-day cycle, with ovulation on Day 14.o, generally speaking, the earliest you can expect a positive HPT is 8 days past ovulation (DPO) and the latest would be about 16 DPO. It is possible to get a positive test earlier or later, but not as common.
