Late period 2.5 yrs after tube tied

Rachel
Hi everyone so I'm a little nervous, I had my tube tied 2.5 yrs ago the day after the birth of my third child. I am never late, periods are always on time and always with obvious period symptoms. Well I'm five days late my beasts have been extremely sensitive and sore for a week now, I'm bloated, exhausted, and irritable. Today I had super super faint spotting more like a very very light pink discharge a few times after using the bathroom. I'm wondering if it's worrying about the possibility of being pregnant or not. My tubes were cut, tied and burned.
