Again, not trying to be mean to you, OP, but... It's your right (and responsibility) as an owner to know how to run some basic diagnostics for yourself. Regular annual exams, incl. a fecal float, and consistent heartworm/flea/tick preventatives keep you pretty clear of most problems. Dogproofing your house and crating your dog when they're left unattended prevents ingestion troubles. A minor spot of red blood in stool (not dark/black "coffee grounds" looking), once, is something to flag for follow up, not panic about. So if you don't have evidence that your pet got into something problematic, or reason to suspect illness, your options are time or expensive labs/x-rays etc. and it's usually okay to wait.
Next time you think your pet might be ill, try this:
Is your pet...
1) willing to eat regular food
1a) willing to eat a favorite snack
2) drinking water
3) urinating/defecating on a normal(ish) schedule
4) sleeping regularly (not too much)
5) behaving normally (not panting, shaking, whining excessively, liplicking, etc.)
If your pet passes all those, you're probably fine to just wait. Make notes. Take photos of anything that seems off, document and observe. White rice and canned pumpkin (or dried:

If your pet fails those, seems distressed, is agitated and unable to rest, or the opposite (can't be roused, won't engage, seems checked out), you might be dealing with an emergency. Know how to check some basic vital signs (temp, capillary refill/pinch test) and gently "pat down" your pet if you suspect pain/tenderness to try to figure out what may be going on.
When things are truly an emergency, you'll know. There's no ambiguity. Things are just WRONG. Not "I think this might be a problem..." it's a PROBLEM. If it's not that, you probably have more time than you think, and the more information you bring your vet, the better chance you have of a successful outcome without a burdensome bill.
