Breast dimple

So in the past week I have noticed a very slight dimple in my breast. I have made a drs appointment to get it checked, but was wondering if anyone else has had this with breast changes while breastfeeding. I'm almost 29, so I know age is in my favor that it's not cancer, but I'm scared as my mom had breast cancer at 55.

Hoping and praying I'm one of the people who it comes back as nothing.
