Did your previous smear test showed any signs of cancer in cervix? Otherwise, there is no need to worry so much as your symptoms suggest inflammation of bladder and urethra and can be due to urinary or genitourinary infection
(rather than cancer). Please do not be alarmed. Bloating of abdomen is most likely due to common causes like gaseous distension from infections, indigestion
changes. Please get your urine examined for infection along with routine gynecological testing and smear.
Wish you the best!
