The first issue you encountered sounds strange. I think you should address it publicly, should it arise again.
Whatever made you blush when speaking with your frum patient, probably just rolled off her back. Once a woman has a baby, she just doesn’t think about things the same way. You’re single, so you feel differently (at the moment). However, I think that will change soon enough, being in the medical field.
It sounds like a very stimulating environment to work in. Enjoy!
