My 3 month old baby was around an entire family who unknowingly had bronchitis last week. Will she get it?

I had my daughter around my sister and her child last week, she told me her son was having allergy/asthma problems so he was not a threat to her, come to find out it was bronchitis. My sister developed bronchitis within a week of that. Before I knew that my sister held my daughter for about an hour straight. This week my daughter has been coughing a couple times a day and sneezing throughout the day, normally she sneezes a few times a day. I am super paranoid of my baby getting sick. She is exclusively fed and I know the antibodies she is getting are helpful, but are they enough to fight this off? My daughter only had one of her shots at 2 months, the rest we are holding off until she is just a bit older. I am also a stay at home mom so that is part of the reason we are delaying her vaccinations. Should I maybe call her doctor and have him look at her or am I being paranoid for nothing?? Any advice would be greatly appreciated! I am a first time mom so I get nervous a lot!
