Pneumonia? Used a nose suction for babies on baby with cold. Suction is powered by mouth.

Late 30s female, breastfeeding, 4 months postpartum. Domperidone 10mg 3xdaily. Germany.

I feel very stupid. I used this "Nasensauger," https://www.rossmann.de/de/baby-und-spielzeug-babydream-nasensauger/p/4305615972114 on my baby who has a cold. I inhaled directly into my lungs and already have a sore throat and headache after a day of using this. I'm pretty healthy but if breathed this in directly, will I have caused a lung infection?

Thank you.
