Your urine being clear is GOOD SIGN. You want it to be clear, that means you are getting enough fluids in your body and it is ridding of all the toxins within. You cannot die from drinking the amount of water you are currently consuming.
The regulation of both the ovarian and uterine cycles is the function of several gonadotropic and ovarian hormones. Among the most important of the gonadotropins are luteinizing hormone (LH) and follicle stimulating hormone (FSH), while the most crucial ovarian hormones are the androgens, estrogen and progesterone.
Depending on how much and which progestin you use or take, a progestin can have different effects. For instance, high doses of progesterone are necessary for some women to continue a pregnancy while other progestins in low doses can prevent a pregnancy from occurring. Other effects include causing weight gain, increasing body temperature, developing the milk-producing glands for breast-feeding, and relaxing the uterus to maintain a pregnancy.
