I don't think you need to contact her unless you really want to. You are still at the 'getting to know you' stage and like you say it's understandable she is on high alert, but from what you say she's not intending to take any action, so perhaps this is one of those trust-building opportunities where she can see that you don't act on the ideation and not be on such high alert next time. Try not to worry about stressing her out; she didn't go into this line of work unaware that it would sometimes be stressful and/or worrying.
