Hello,
If the doctor only used 20% TCA (this is really not very strong) much of this should improve with time and sun avoidance/ sun screens (SPF 30 plus). Bleaching creams and/or dilute Retin A may help but I am not sure I would recommend them when you are trying to get pregnant.
What does your surgeon say? Are you still seeing him or her? Hyperpigmentation after peeling really requires a doctor's continued examination to change to the things that work well for you. People vary.
Best Regards
