bronchitis and allergies 29 weeks pregnant

So this pregnancy has been tough for one I've had an allergic reaction to our daughters guinea pig and a constant runny and stuffy nose for almost 7 months so now I have bronchitis and I'm already taking protonix, my vitamin, Miralax 2 times a week, Tylenol to get me through the day because I work full time and I am a mom to a 4 year old and I feel miserable, I have my one cup of coffee a day, now my dr Said it's ok to take Zyrtec, than I had this cough it's ok to take mucinex, and now a z-pack! And I'm moderately anemic with a scheduled c.section so I have to take iron too. I don't want to pump my baby full of all these medications and shit like I'm so torn with all of this. Has anyone else had experience with all these medications?
