In most cases, bleeding caused by implantation will be either brown or light pink in color. The flow is very light and will only last a short amount of time. Some women will also experience some cramping as well. Bleeding will come and go, and be very light.
A chemical pregnancy is simply a miscarriage that occurs very early on in a womanâs pregnancy. Often, this is because a woman was able to obtain a positive determination of pregnancy from a test before her period typically occurs.
An estimated 15 to 20 percent of known pregnancies end in miscarriage, the loss of a pregnancy before the 20th week. The actual number is likely higher, because many miscarriages occur very early on, before a woman knows she is pregnant, and may simply seem to be a heavy period on or near schedule. Most clinically recognized miscarriages occur between the seventh and 12th week after a womanâs last menstrual period.
