Re: I need major help.....
When a woman gets pregnant, she needs a certain amount of body fat to maintain the pregnancy. The body will stop menstruating if the body is not equipped to become pregnant and maintain that pregnancy state.
That said, there's nothing wrong with it. My mother was a marathon runner with about 16% body fat and her cycle lasted a day or two and was so light it basically amounted to spotting. But she was done having kids, too, so it didn't really matter.
I'm super glad you got the ok from the doctors!! Good for you. Some people don't take the time to make sure. It shows you care about yourself.
