Breastfeeding mom with sudden sinus congestion

Hey ladies!!! So I woke up yesterday early with a sore throat & stuffy nose after a night out but I thought it was simply dry throat from breastfeeding late nights & not staying hydrated. It continued even after water + hot tea. Then, mucus began draining from my nose & throat. I felt my body trying to fight a sinus headache. I’m a firm believer in herbal medicine/remedies curing all DIS-eases so I’ve been taking electrolytes, ginger, elderberry tea to fight the congestion. However, I’m worried that I will pass my symptoms off to my 3m/o baby through breastmilk since I’m feeling ill. We keep Enfamil

plant-based formula as backup whenever my supply is low but she prefers my breast for comfort. Should I give her the formula until I feel better or continue breastfeeding??
