Look its as simple as this, this is what the dr gave to break down the
weeks and months, there is more than four
weeks in most months sometimes there are five
weeks and there is more than 28 days in a month most have 30 and 31 if you don't like this chart don't go by it point blank period then end. But you need to get off my post being rude to everyone on here especially the ones who say the chart is helpful.
