Hi John
From what I can see in your account, the points from your subscription are usually added on the 29 or 30 of each month.
There is a small difference beween the date of the start of your subscription and the date your points are awareded, but don't worry it does not make any change to the number of points you will receive, even if at one point you decide to cancel your subscription.
You will of course receive 30 points per month of subscription.
