Go see your doctor: Regular use of NSAID (Non-Steriodal Anti-Inflamattory) medications like Advil(ibuprofen) can cause thinning and damage to the stomach lining leading to ulcer formation and bleeding. Bleeding ulcers can be very very dangerous, please get seen as soon as possible.

No it is not common: No it is not common to have streak of blood when moving bowels I suggest you consult your Doctor to find the cause of rectal bleeding.You may need a referral to GI Specialist and may need colonoscopy
