Could I be pregnant or is it stress?

Erica

Hey guys I had a tubal ligation 6 months ago and now my period is 3 days late. I also had spotting a week and a half ago for two days and now spotting today (3 days late) but nothing else besides a very small amount of spotting. I have also had random nausea which I chalked up to possible food poisoning because I’ve been having off and on stomach aches the past couple days. I also have been very moody, and want to vomit whenever I think about or eat a mushroom. I’m also very tired the past couple days to a week and always taking a nap during the day which is new for me. My partner thinks it’s impossible to get pregnant with a tubal ligation but I’m starting to worry. Help 😱
