Two of my mom's friends got pregnant after a tubal ligation. It's not common but is possible.
Honey, don't shout, just go get a home pregnancy test. The likelihood is that if you have had a tubal ligation, you are not pregnant. Sore breasts can come from other things, like too much coffee. Get a sensitive home test and use first-morning urine. In the meantime, get rid of the mean guy. It's doubtless better for your kids, and is certainly better for you.
