It is unlikely the blood in your urine is caused by stomach acid.
You should see your doctor as there are a number of possible causes.
It is most likely cystitis (which may cause a burning pain when you urinate) but could be kidney stones (which can sometimes be painful), urethritis (often caused by sexually transmitted disease, chlamydia), enlarged prostate (usual in older men causing more frequent urination or difficulty in urinating) or it could be a sign of cancer of prostate, bladder or kidney if you're over 50. However these cancers are slow developing and treatable if detected early.
