I went rogue and need help now

I am currently in week 9 of using tretinoin 0.025% gel. I started off with twice a week and worked my way up to every other night. I was prescribed tret for comedonal acne which was getting progressively worse without treatment. I purged almost immediately after starting. However, even by week 6-7, i noticed no real change in my comedones but at least my purge had significantly reduced. This was when i went rogue and changed my routine without asking my derm.

I got frustrated and wanted to speed up the process, so started using tret every night (this was week 8). And also started using benzoyl peroxide 2.5% gel as spot treatment everyday in the morning. My active acne calmed down where i used BP as spot treatment but overall, i’ve started to purge again in the 9th week of tret usage. And there is zero to very unnoticeable improvement in the comedonal acne. The rest of my routine is only moisturiser and sunscreen (both non comedogenic) and salicylic acid facewash at night. What am i doing wrong?

Should i remove BP and dial back the tret to every other night? Or should i persevere? More importantly, shouldn’t i have seen some improvement in my comedones by now? Plis help.
