I agree, give it a bit longer, it does sound like she's taking a thorough history first, which might be a really good sign!

My T would only go over (even 3 or 4 minutes) with mentioning it, and both agreeing it briefly. She's good at holding the time boundaries, consequently she is almost never late for my start time! For me personally, that's a good sign that your T is hot on the timings.
