Should I quit Propecia??

[SE19]

Hey guys,

Ive been on Propecia for 3 months now and im not too pleased with whats happening. In the last 3 months ive noticed my hairline getting noticeably worse. The widows peak seems to be growing more and more narrow as the hairs on the edges seem to be falling willy nilly. The hair just behind my hairline seems to feel and look slightly thinner too, aswell as the crown feeling and (in some lights) looking thinner.

Im 19 and feel like this has progressed far too quickly in the last few weeks, so what are my options?

Is the hair shedding and will probably grow back thicker?
Is it not working? should I quit and look for an alternative?

any feedback would be great.
Regards, SE19
