Hello. I have been having some back side pain, stomach pain, and head aches. I also have expierenced having the earge to pee and sometimes when I go to the bathroom only a little urine comes out. I have been drinking water regularly and I drank some Cranberry juice and it kind of helped! I don't know what is wrong! Can you help me please?

This could be a bladder infection. You need to go see a doctor.

Yes, cranberry juice can help prevent UTIs (urinary tract infections) which can go all the way back to the kidneys if really bad, but you really need antibiotics if it is that.
If you were male, I'd suggest enlarged prostate (BPH if benighn) but from your ID it looks like you are female.
