If it is indeed a miscarriage, the bleeding will become more consistent soon as it seems you have been bleeding. Have a lot of pads handy if this is the case. Otherwise, I have heard that 20% of pregnancies have some form of bleeding, and not to worry. If it becomes heavy, call your doctor. I didn't feel pregnant with my first child for quite some time. It is early for you yet.
