User profile won't display for current user

Hi, I've added a user (devise) and a profile to my app. The problem is
that I can't display the profile for that user. It tells me that there
is No route matches [GET] "/profile/1"

I wonder if anyone can point out where I'm going wrong, and why?

routes.rb
Rails.application.routes.draw do
  devise_for :users
    resources :profiles
    resources :appointments

  root 'page#home'
  get 'page/testimonials'
  get '/signedinuserprofile' => 'profiles#signedinuserprofile'
  #get 'page/home'

profiles controller:
class ProfilesController < ApplicationController
  before_action :set_profile, only: [:show, :edit, :update, :destroy]

  # GET /profiles
  # GET /profiles.json
  def index
    @profiles = Profile.all
  end

  def signedinuserprofile
    profile = Profile.find_by_user_id(current_user.id)
      if profile.nil?
        redirect_to "/profile/new"
      else
        @profile = Profile.find_by_user_id(current_user.id)
        redirect_to "/profile/#{@profile.id}"
      end
  end

application controller:
class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception

  def after_sign_in_path_for(resource)
    "/signedinuserprofile"
  end
end

sessions controller:
class SessionsController < Devise::SessionsController
    #after_sign_in_path_for is called by devise
    def after_sign_in_path_for(user)
        "/signedinuserprofile" # here I provide the path for the user's
profile
    end
end

I think you would use GET /users/profile/1
