Site not showing that users logged in after they register

I have a site that has some content for registered users. That content is uses
if (is_user_logged_in()) {
}else {
}

After registering it redirects you to a questionnaire, the header shows that you are logged in. Then if they continue on to a page after that, it says you are not logged in until ctrl+R refresh

Users don’t know to refresh the page, I tried wp_reset_query() before is_user_logged_in and doesn’t seem to work.

I don’t have any cache enabled. It is getting annoying. Any ideas will be greatly appreciated.
