Long cycles after MC

I am currently in the 4th cycle after MC in June and have had the last 2 cycles very messed up. Last one was 34 days long and this one AF lasted 3 days longer than normal and I'm on CD 25 now and just got a positive LH Surge. My dr told me if in 2 more cycles they didn't go back to normal he'd have to put me on BC for 3 cycles 😩 Anyone else in the same situation? Need some encouragement.
