Failed MA - second guessing decision now - USA/New England

Last Friday I had a MA. Had to take the miso a second time because nothing happened with the first dose. I had bleeding and cramping for about 4 days, no clots. HCG last Friday was 61, last night was 566. After speaking with PP on the phone today they think that I’m still pregnant (also having pretty strong morning sickness). They want me to have the in clinic procedure next week. Part of me is saying maybe this is a sign I should keep it, the other part of me is saying my reasons for having the MA have not changed and besides after taking the medicine is it even possible to have a healthy baby/pregnancy at this point? What do I do? What should I expect from an in clinic procedure?
