Any of you lovely ladies know of any good PREGGO SAFE cold remedies to take?

I take my vitami s every day & eat pretty healthy well-rounded foods (in moderation due to morning sickness) but this passed week I havent gotten enough sleep cause I've been taking care of my moms son (my brother) who's 4 (yes, my mother is old & cant keep her legs closed 😤) & severely autistic. None of my kids are autistic so it has definitely been different for us.

Anyway, cold remedies? I usually just take alka seltzer but it has asprin in it...
