Of course! You can change your plan any time during the current monthly subscription.

If you upgrade your plan partway through a monthly subscription, you will be immediately charged the pro-rated difference in prices between the old and new plans.

If you downgrade your plan partway through a monthly subscription, the unused amount that was previously billed at the start of the month will automatically be rolled over to subsequent months as billing credits. These billing credits will offset your subsequent monthly bills. You will only be billed for the new plan once these billing credits are used up.
