Canceling Astrology & Palmistry Coach app

I subscribed to the Astrology & Palmistry Coach app for the free 3 day trial. I would like to cancel it before I am charged the $9.99 a month. My subscription charges me on November 6, 2018. When I got to my subscriptions on my iphone, it shows up, however, when I click the app subscription, it doesn't show anything or allow me to cancel it. I don't want to waste money on this app as it is not worth the money. I have googled how to cancel my subscription and have followed all the steps but it won't give me the option to cancel it.

Please help!
