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).
Letâs say your fertilized egg implanted at 8 days past ovulation (dpo). If you have a normal 28 day cycle, that will be 6 days before your period is due. Maybe by the end of the day, your hCG level is at 5 mIU. If you wait two days (4 days before your period), your hCG level should be around 10 mIU. Depending on the sensitivity of the pregnancy test you are using, you might be able to get a very light positive result at this point. Itâs not likely, but it is possible.
