Manually changing renewal date after signup

I have 3 month and 6 month prepaid subscriptions on my website. With all my subscriptions, I do a sign up fee so I can get payment for that month straightaway because I send out my sub boxes out the same month. I also have a 5 day free trial so people dont get billed twice in one month.

The problem is with the 3 month and 6 months, when they sign up they pay upfront, but today (which is my renewal day) they got billed again. For the 3 month I guess I can do 65 days free trial which means when they sign up at any point in the first month, they wont get charged again for another 3 months. But what about the 6 month one, as it says you cant put more than 90 days.

How do I stop the 3 and 6 months= subs from paying the sign up fee and getting billed again the next month on renewal day?
