I am pregnant with my
first as well. They say it is common in some women to have some
bleeding during 1st trimester and early on in the 2nd. I experienced the same thing. Woke up and there was really dark red blood. They say when your uterus expands, it can expel old blood. You may also experience some cramping. As long add your bleeding is not profuse, where it fills up a pad, heavy cramps and maybe uterine tissue you should be just fine.
