Female: Period Began On The 22nd A Week And Two

Female: Period began on the 22nd a week and two days ago. Consistent flow lasted two and a half days then slowed to spotting and I thought stopped. I've still been noticing sometimes after I urinate I still will find blood spotting, brown or a red drop or two.. I'm wondering if this is normal?.. My period was about five days later than usual this las time..
