Need suggestion on mole getting tested.

A few years ago I developed a mole on my back,which I didn't pay much heed to,it wasn't growing or painful and my mother having a similar mole at the same place made me think it can be genetic but today I discovered another similar mole not far from the previous one and what It seems like another one starting to develop in my upper arm near to the previous one again.it seemed a little suspicious so I looked up reason of mole growth and it said that they can be early signs of melanoma.i don't want to get stressed and start freaking out based on these assumptions so I wanted an opinion on whether they look benign or should I get them tested and consulted by a dermat.i am attaching photos of the moles with this post.please kindly help and suggest me the right thing to do.i would be extremely grateful if I can be guided to consult further or to relax regarding this issue.
