Freckle

I had a baby in summer of 2019 and breastfed for 4 months then started antidepressants (stopped breastfeeding) and gained a TON of weight from the antidepressants, so my hormones were all over the place for 18 months (not even including the 9 months of pregnancy). So I’m assuming this freckle is from all of that. I first noticed it in March of this year. It isn’t changing shape or getting bigger, it’s 2mm. Do you think I should have this seen by a dermatologist?? It’s hard to tell but one part sometimes looks dark brown and another part looks lighter dark brown, if that makes sense. It’s actually on my areola, thats why the skin texture looks so weird.
