Volts and amperage together basically combined in a formula to determine the number of watts, but they are not specifically related to each other. As per Ohm's law V=IR where V is voltage, I is current and R is resistance. since Voltages is equal to current times resistance than makes them directly proportional to each other and therefor related.
Cervical Position. During menstrual bleeding, the cervix is normally low and hard and slightly open to allow the blood to flow out. It feels like the tip of your nose. After your period stops, the cervix remains low and hard and the opening to the uterus (uterine os) remains closed.
I normally get eggwhite cervical fluid a couple days before I start my period too, but I also get it about 13 days before i start my period too. Ovulation is also accompanied by ovulatory pain (sometimes) and a temperature spike the day after the egg is released.
