Have not had a bowel movement in 2 days i have pain in my stomach feel like i don't wanna eat feel like i'm gonna vomit appetite has decreased?

OTC then Doc: I would try some over the counter stool softeners plus or minus laxative. If not successful within 24 hrs or worsening symptoms or fever.... Head to your doctor.

Drink water: Drink plenty of water - at least 8 full (8oz) glasses and continue even after this ends. Also, don't eat except some prunes and/or drink some prune juice. OTC laxatives can be too harsh for some, but if you know they suit you - that might be needed. If it is not better by a day or two - you need to see a provider to help clear it up and since it's a holiday - that may be hard. Best wishes!
