i went to get a pap today and my dr and his assistant both did an examination of my uterus. They both told me my uterus was very large and asked when i should get my next period. i told them it should be arriving anyday now. I have gotten my tubes tied in may of this year. when dr was leaving room he told me to call him within the next week when i havent recieved my period. pretty sure he thinks im pregnant. scary as hell. i have two boys 10&3 and two step children 3&1. I dont want to be pregant but if it happens it is what it is...but i dont feel pregnant...what are the chances if my uterus is large??? could it be something else??
