Light period after d&c

Lb • 🌈🌈 had our lil miracle on March 1st, 2020 after 1 natural loss, 2 failed IUIs, 1 miscarriage after IVF and one failed FET. Diagnosed with MTHFTR, Leiden 5 Factor and Advance Maternal age. Miracle 2 is a girl! She arrived May, 18th, 2023.
I had a d&c in June. I should have been 10 weeks but baby stopped growing at 6 weeks. It took me 8 weeks post surgery to get AF. Every period since has been super light 1-3 days and only brown spotting. My doc says my body just takes longer to get back to normal. Anyone experience anything similar and go on to get pregnant or should I be concerned? What was your period like post d&c? Thanks in advance!
