Acid during pregnancy

G ✨ • Mama to 2 little girls. 2 years old and newborn • May babies

I just ran out of my prescription Pepcid from my midwife. Haven’t had it for 2 days now. Today woke up feeling stuffed up, in a fog and tired, like I have a fever but I don’t at all, and have a weird feeling in my throat when I breathe kind of like when you breathe in super cold air. I had all of this before I started the Pepcid pills too. Can acid do these things during pregnancy?? It’s the only thing that makes sense.
