So stressed so early!

This is my last pregnancy I have a beautiful 11 yr old daughter and I'm 31 now and about five weeks pregnant. I've only known since Nov 29 and it feels like everyday is a struggle. I just keep bleeding. Went to er two days ago and my level was 702 and the gestational sac was still intact. I just won't stop bleeding it's not super heavy but it slow and steady. I need to get my hcg level tested again and the Dr. Doesn't want to take me bc I haven't had a second hcg check the all tell me to go back to er. I mean it so horrible and invasive at the er. I'm just so freaking frustrated! Any advice would help! Thanks
