Thanks for your query on health care magic.
Your symptoms of repeated urge to urinate suggests urinary tract infection
Spotting could be due to local injury
or abrasion which needs physical examination by a Gynecologist.
I recommend you to:
1. Get a urine routine and microscopy.
2. Urine culture and sensitivity.
3. Antibiotics and urine alkalizer
4. Drink lot of fluids.
Hope this helps,
