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.
The average menstrual cycle is 28 days long. However, a normal cycle can be shorter or longer than this. It may be anywhere from 21 to 35 days long. Most periods last 3 to 5 days, but anywhere from 2 to 7 days is normal. Menstrual cycles may happen around the same date every month or they may be irregular. A menstrual period is considered late if it hasnât started 5 or more days after the day you expected it to start.
