Miscarriage Bleeding. How long do you bleed after a miscarriage? It is normal to bleed for up to two weeks after your miscarriage has occurred. This bleeding may be a steady flow, or may take a stop and start pattern, where you do not bleed for a day or two and then begin again. If your bleeding is very heavy after 2-3 days, please contact your doctor as you may have some retained tissue that is causing the heavy bleeding. When can you expect your next period after miscarriage? You can expect your period to return in about 4-6 weeks after the loss of your baby.

The Body in Space. The human body is uniquely designed to live in Earthâs gravity. In space, the body begins to adapt to the microgravity environment. NSBRIâs science and technology program is addressing ways to reduce or eliminate many of the changes to the body that impact an astronautâs ability to perform well in space and that might impact their health after returning to Earth.
