Pregnancy after tubal?

Trista
Ok ok so I had a tubal done in 2014 during a cesarean. I've been sleeping with one guy.. but for the past few weeks I've had all the typical pregnancy symptoms and my period is 4 days late! Normally before I start my monthly, which is very regular. I usually get discharge, cramps, cravings. I've had NONE. I'm so nauseated I can barely keep water down. Could I be pregnant?
