Is my hairline receeding?

[FK9]

Hi, I am 23 years old and wondering if my hairline could be receeding, I would consider my hair to be generally thick, don't have any problem with thinning hair but my hairline seems to be forming an M shape lately, I had a bit of a dip in my hairline since childhood or what people may call widows peek but lately, that shape is getting more prominent. My Dad is also completely bald, that also scares me a lot, can Finasteride help in this? I heard it doesn't work on temples and receeding hairline.
