Its not normal to have pain continuously.
You need to look for problems like
1) Pelvic inflammatory disease
- if you have symptoms like white discharge, associated backache
2) Urinary infections - associated symptoms burning in urine, increased frequency
3) Bowel related - increased stool frequency
Get your examined and get your urine tested - will clear the reason
Hope this answers your query.
