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.
Cervical Mucus Before Period. Throughout your monthly cycle, the cervical mucus in your vagina will change. Right before your period, the cervical music will be different than it is at the end. This does not mean that anything is wrong with you; it is completely natural for things to change throughout the month.
