i would go to the ER maybe a different one.. and let them know your pregnant, and you have pain and bleeding, i went to the ER just with pain and they did a internal exam, took blood, urine, gave me IV fluid to hydrate me,herd the heart beat on a doppler, and a ultrasound to make sure it was eptopic... and maybe let them know you might be having an eptopic...
i would walk in there and say i didnt know how far along i am and i might be having an eptopic... they might look for it then or look for another reason, thats what i did with mine and they did every test they could to find out whats wrong.
