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 few days later I had really strong implantation cramps, then a few days after that I took a test. And it was positive!! So i know for a fact u can have symptoms before the egg implants
