that's not your fault sweetheart, i dont think hardly anyone "stops" bang on the minute/second that their session "offically" finishes, i would have thought ending a session right is just as important as what happen's during, that's quite stressful to know though that sessions are back 2 back like that, its very easy to lose total sense of time, & you shouldnt have to worry if you run a few minutes over, suppose all T work differently, mine said to me at the start if i arrive early that's cool as he alway's has 30 minutes break between sessions, not just to avoid this, but so he can get his head straight, she must be wonder women!
