Help me with my dog if you can..

TW - GRAPHIC DESCRIPTIONS OF VOMIT IN THE NEXT PARAGRAPH.

does anyone have any recommendations on how I can help my puppy? (She's not rlly a puppy but she's my child. One of the reasons I'm still alive.) She's two years old, 30 pounds. The cutest blue heeler. But last night she began v0miting. It almost seemed violent.. There are about four stains the size of my foot in my room. I'm extremely worried.. My mom thinks she just chewed up something she wasn't supposed to (there's these red plastic chunks in the puk3.) But even then I'm still scared shitless. Something's wrong. We tried giving her a pepcid, as they're dog-friendly. (medicine to help ur stomach) But she wouldn't eat it. My mom says if she's still vomiting by Monday we'll take her to the vet, but that just upsets me. Like, is her not puking every four hours concerning to you? Can someone please help or give me advice on what to do..I'm very worried. 

Update - she vomited again last night, this is about the 7th or 8th time since yesterday night. As I was picking up the vomit throughout the day(s), it looked like there were bits of carpet in it. In more vomit, there were pink/reddish plastic chunks in it. I'm just so confused because usually that kind of stuff comes out when she poops. But then again she hasn't pooped since like yesterday morning. But even then I don't know how long that poop had been sitting there. (we have dog pads in our house instead of taking her outside bc our fence is still destroyed from Hurricane beryl) we're taking her to the vet later today for x-rays, I just hope it's nothing bad...

Update #2 : we took her to an emergency hospital, they ran tests and x-rays. Apparently there's an object stuck in her stomach. Somewhere in there, and it isn't passing through. She's very dehydrated, lacking fluids...she's gonna need some sort of "exploration surgery/procedure." whatever that means..right now we're driving to a farther hospital that can do an ultrasound to see how bad it is. It's about an hour away. I'll post updates when I get there and what they say. 

Update #3 : SHE'S FUCKING VOMITING. I THINK THERE'S BLOOD? IT'S A CRIMSON COLOR. SERIOUSLY HELP.
