Recurrent pregnancy loss

Hi,
I’m 38 yo and I live in Norway, and here the doctors are quite conservative.
I have had 5 miscarriages after natural conception. 1 at 5w, then had my son in 2021, then 4 the last 12m, one at 4w, one at 5w and now to missed miscarraiges at 9w. The last MM this week. I have minimal endo removed with laprascopic surgery in 2020, and I just got a RA diagnosis in january. I’m on 50 mg Enbrel pr week. I’m planning for IVF, but don’t want to just pay for an expensive miscarriage. Is there anything I can ask my doctor for? Where should I start? Should I get another laparascopic surgery? Or is maybe prednisolon wise?
