Copernicus did not explain, however, exactly how he came to the conclusions that the problem lay in geocentrism and the solution in heliocentrism. As a result, experts have been trying to reconstruct his path to the heliocentric theory ever since.
There Is A Wide Range Of Normal. Normal menstruation can last from one to eight days. For most women with regular menstrual cycles, their period will last on average three to five days. But that doesn't mean that anything is wrong if your period is a few days longer or shorter. Your period is unique to you and how much you bleed and for how many days you bleed will not be the same as anyone else.
How many days should I have between periods? I don't have mine at the same time every month. The average menstrual cycle lasts 28 days; however, any cycle between 23 and 42 days is typical. Depending on how long yours actually is, you may not have it at the same each month. My cycle is about 30 days, so mine usually comes around the same date, around the eighth to the tenth day each month. You and me both!
