Breast pain, period just finished, am I overthinking?

I been having breast pain for the past few days, maybe 9-10 days.

I usually don’t

I’m not pregnant

I’m scared to think it can be breast cancer since my mother was diagnosed with it before the age of 45 and my doctor said that me and my sisters have a chance of getting it since our mom had it at a young age.

It’s my right side. It’s just a dull pain and when I feel it for lumps , it hurts more .

I’m scared to go to a doc because I somewhat don’t trust doctors these days.

My mom and her friend were fine and randomly went together one day to get tested and both ended up being diagnosed and went thru hell.

I feel like even if I don’t have it they’ll falsely diagnose me with me.
