Sour stomach

Nina • Mother to a wonderful 7 yr old boy. 40 and pregnant 💜💜💜. Suffered 3 miscarriages and one passing at 15 weeks from Trisomy 18. Keep Hope 💜

I’m 7+3. For the last several days I have had the worse sour stomach. I have taken tums and probiotics and no improvement. Anyone dealing with this? Have you done anything that worked for you? Thanks!
