3 months post breast reduction, having some issues. B to D cup.

I had a BR in May, At first I fit comfortably in a Bcup bra, and was over the moon happy with my results. I'm now a Dcup, the increase is noticeable and I hate it. I had a few complications during recovery, wound dehiscence, slight infection, recurring seroma on left side. I also have PCOS, fibrocystic breasts, and as per my GP, starting perimenopause. Could hormones cause breast growth? If I have a 2nd reduction how can I ensure lasting results? How long should I wait, will OHIP cover it? Thx!
