I Received A Positive Urine Pregnancy Test May 30, Started

I received a positive urine pregnancy test may 30, started bleeding heavily may 31. Went to my pcp on June 8th still had positive urine test and also a positive blood test with an hcg beta count of 908. As well as a pelvic exam showing my cervix still being closed and no signs of miscarriage. On june 15th i had another blood draw with a count of 2397. My pcp says I'm deffinately pregnant and to continue with ob. I scheduled ob appt and they will not see me until 8-10 weeks regardless of bleeding. I have had 1previous miscarriage and bled the entire first trimester with my second child. My daughter is 18 months still breastfed and therefore i have not had a period. *****************************************Should i go to the emergency room and ask for a transvaginal ultrasound to confirm this is a viable pregnancy or just wait 3 weeks for my first ob appt that i was told they will schedule a regular sonogram at 12 weeks gestation?******************** With my miscarriage that was how they determined it was not viable, with my daughter i had blood drawn every 3 days to moniter my levels as well as multiple transvaginal ultrasounds until they were absolutely certain baby was thriving and the bleeding ceased. Also i am 2 hrs from the drs i had with my daughter so i am dealing with someone completely new.
