First time hysteroscopy for RPOC

I had an mmc for a twin pregnancy in Jan. Even after taking 2 doses of misoprostol, I still had 14mm of RPOC. The doctors suggested to di an in-office hysteroscopy. I had the procedure done (without anesthesia) and they managed to remove 80% of the tissues. The rest, they said, are adhered to the wall and asked me to continue taking Zoely so it can help it detach. They will schedule a 2nd round after 6 weeks. At this point, I'm so tired and frustrated I don't even know whether I want to do this or get pregnant again.

Has anyone gone through a second round of hysteroscopy? Did it help to get the remaining tissue out? TIA
