I’ve been having a sour stomach & heart burn since last night it’s now 5:16pm next day I used the restroom earlier it wasn’t diarrhea but it was a bunch of poo! The night before I ate a philly cheese steak but that’s something I eat very often and it has never done this to my stomach! I haven’t ate anything but pizza rolls today & a pop sickle because I’m afraid of my stomach getting worse. My son is very active I’m 34w & 6d. I took tums for the heartburn and upset stomach and I’ve drank a ton of cold water but it just makes me uncomfortable to lay down. Any advice?
