I had some bleeding during my first trimester. I thought I was having a miscarriage but baby is great. I am now 20 weeks. I really want to exercise to stay healthy but not sure if it is safe. My dr didn't seem to concerned about the bleeding and they didn't have any answers as to why it happened. It was a sudden gush of blood without cramping and then minor bleeding for a few days after. Anybody have any experiences or feedback?
