Hi L.,
It's great if she tells you after she goes, my kids did that before 2 also, but we're trained til they turned 3. My own experience was that I did not do early training because I didn't feel that having a child who used the potty occasionally, was a tiny bit trained, had accidents, etc was a benefit to me - no patience for the long, drawn out training process, I preferred having a kid in diapers and then training in days or a few weeks.
That said, my method was switching to cloth training pants (at her age, cloth diapers may be better) with the waterproof outer layer. This teaches them that when they pee, they get really wet, and they start to learn what it feels like just before that happens. I made sure to take them to the toilet (I didn't do a pottie for a variety of reasons) about every hour and a half. My youngest is 10 now but when I did this, it took him 2-3 weeks to stop going in the training pants and start waiting til I took him to the toilet but after that, no accidents, he figured it out. Those few weeks were rough and messy but in the end, it worked out well. It was still another month or two after before he would tell that he had to go - a lot of parents wait for the child to tell them, thinking it is the first step in the process. I made this mistake with my daughter. It's usually the last step so you don't need to wait to start the process til your child tells you that they need to use the bathroom
Good luck
