I had a tubal ligation after my 3rd child and sometimes it is due to stress or a hormone imbalance. It is highly unlikely that you are pregnant, but it is possible. Most of the time, if someone with a tubal ligation gets pregnant, the pregnancy is in the fallopian tubes. I would suggest going to a doctor to rule out that possiblity, because it is a very serious condition. Also, I did have other problems after my tubal ligations, like heavy bleeding and horrible cramps, severe moodiness, etc. However, after meeting my husband (he didn't have any children of his own, but does consider my 3 from a previous marriage his) we decided to expand our family, so I had a tubal reversal. It turned out wonderfully, we now have 2 more children. We do have to worry about birth control again though, which is a downside to a reversal. Good luck!
