How to know my subscription status?

I bought a 1 month subscription on dec. 14th, being active from dec. 15th according to the payment history. I didn't see any change today, as it should have ended by now, still I was able to watch my todays race in 2D. Does it end at the same day as payed + one month, or is it one month + one day? Or was I using my 2D trials (which I didn't use before paying, as far as I remember).

Unfortunately there is not a single clue when exactly my subscription ends or how long it'll last. It would be nice if something like this could be added to clearly show how many days are left.
