Can Propecia Make My Hair Worse in a Week?

I am a 20-year-old male and just began Propecia about a week ago. I have been looking and feeling my hair a ton since I began the drug. To me, it seems almost as if my hair is worse after starting it? My crown feels thinner to the touch and my hairline seems a little more sparse. I have two questions for you.

1) Is it possible that Propecia can make my hairline and crown thinner rather than help?
2) If so is it possible that it could have done it in a week?

Thank you for your reply

While there have been some rare complaints from people that say they have shedding since starting Propecia, I would doubt that something this severe occurs in a week. You should follow up with your prescribing doctor.
