Pregnancy nausea

So I’ll be 19 weeks on Friday, this pregnancy has been a rough one but I’m still so freakin thankful we’ve made it as far as we have and we continue praying relentlessly that my body will carry our babygirl to at least 36 weeks. With that being said, my nausea has been off and on from the beginning. The last week or so it’s come back tenfold but only AT night and either during my shower, before or after. The nausea meds aren’t working, what else helped yall with nausea??? I need tips and tricks cause I can feel it come even hours before the throwing up actually hits it’s awful!

Thanks in Advance!
