7 weeks and preparing mentally for a loss (help)

I had what you would call a chemical or very early miscarriage in Sept. I’m pregnant again and it started out exactly like my pregnancy in Sept but I didn’t miscarry and my hcg is rising 20 percent every 2 days. I had an ultrasound yesterday and they saw a sac but no fetal pole, yoke, or baby. I had to do following up blood work and my hcg is rising (currently 3059) which is very low for 7 weeks but still rising.

I want this to happen on its own but i never has a miscarriage this late so I’m unsure if this is normal. 4 days ago I started awful cramping and very minor spotting. I expected to miscarry but 4 days later no blood, still rising hcg but horrible cramps. I was sweating last night.

My doctor wants one more round of blood work, another ultrasound before she starts talking d&c. Is the cramping normal? I did have awful cramping with my 2nd pregnancy that resulted in a healthy baby. This cramping is similar but more than likely without baby. I hate to have people rehash the worst time of your life but I’m in pain and just want to know if what I’m feeling is normal?

I would ask this on general pregnancy board but as someone who experienced a loss I know the reality that I’m going to experience another one. Every time I ask a question over there they give an hopeful response which I don’t need, I need a realistic one.
