Anyone taken z-pak in 3rd trimester?

I’ve been fighting what I thought was allergies at first for a couple weeks now. Yesterday doc said it was likely a sinus infection and prescribed a z-pak. I’m 32 weeks + 6 days today. I trust her judgement but I hate taking additional meds if I may be able to just power through this without them. This is week 3 of the crud. Surely it passes soon. Anyone else taken a z-pak in the 3rd trimester? Any side effects (tummy issues/bathroom breaks/etc)? Thank you!
