Yes, if you're vaginally bleeding you need to be seen immediately. Bleeding while pregnant isn't normal (though is common) and should always be evaluated by a doctor.
If you are bleeding vaginally dont waste time on here go get checked out.
No I go in tommaro but the other thing is when I went it hurt and there was bleeding associated. not hemorrhoids or bleeding from the rectum, but blood that dripped from my vagina (again sorry tmi)
I wouldn't think it's due to dilation. More than likely its due to the pressure on your lower body and normal aches and pains associated with pregnancy. Have you asked your doctor about the pain?
