Vidcast:   https://youtu.be/DSXxaY3BYdA   Women with a miscarriage history attempting to get pregnant may lose the fetus to aggressive exercising even before they know they are pregnant.  Epidemiologists at UMass-Amherst studied 785 high risk pregnancies in young women with one or two previous miscarriages.   Seven percent of the women suffered yet another miscarriage just as their pregnancy was establishing.  Those who lost their fetus at the time it would be implanting, the risk of loss was two-fold greater in those women pursuing moderate or intense exercise regimens.   If you have a history of miscarriage, avoid any excessive exercise during the first month even before you know you are pregnant.   https://www.fertstert.org/article/S0015-0282(19)32497-5/fulltext   #pregnancy #miscarriage #miscarriage
