About 6 years ago i had an eptopic rupture. The dr did a tubal ligation on the remaining tube. Two months ago i had a normal period. Last month i had some clotting and very little bleeding. Now my breasts are tender, i am nauseated all the time, moody, extremely tired, and have had mild cramping. Could i be pregnant?
