Staying strong that God is helping me through this, but Completely confused/so frustrated with the doctors right now... HELP!!!!!!!!!

So I am going to ask this ahead of time. Please understand I'm trying to stay positive and my heart and mind has already started grieving for a miscarriage. So please be sensitive to the situation.

So heres my confusion and frustration. Well I've had two doctors already rule out ectopic pregnancy. But I have literally been living in either hell/nightmare for 12 days going on 13 days tomorrow. My levels went down from 164.6 to 128.5 withing a week. But today for some reason they have gone up to 187.5 which is higher than when I first got my levels checked. What's confusing is I still have yet to see a ob supposed to go on the 14th to the midwife clinic at the hospital for my first visit. But since my levels went up they wanted me to go back to the er to get checked out. And the doctor there tried saying my symptoms were all signs of early pregnancy. But then looked at my levels and pretty much said to have hope for a healthy pregnancy but be prepared for a dnc also. But refused to do a ultrasound. And was the third doctor to rule out ectopic pregnancy and diagnosed me with a threatened miscarriage.

So my question is has anyone ever been through this and the baby be ok? Family and friends are beginning to wonder if I'm miscarrying a twin and that's what is causing all the confusion. I'm not in pain, I'm spotting but not bleeding enough to really get anything on a pad, really the only thing that's off is my levels. And still having heavy pregnancy symptoms.
