21 and balding need help!

[Gsm1005]

Hi I'm 21 and I'm getting a receding hairline I've noticed a slight v in my hairline since about 19 but never thought about balding now it's starting to get more noticeable and it's driving me insane can someone clasify me on the Norwood scale and should I start adding more to my hairloss treatment I've been on propecia for about 4 and 1/2 months and I do not believe it's working I will post pics below. Thank you for any help and please excuse my blank post I made before this one. And to add on I've felt my hair has just gotten thinner in general but I'm not sure

you are not balding. Your hairline is receding. you need to start treatment immidiately.
