I had my tubes tied five years ago, I have always had a regular period. I am now three months late on my period, my belly is looking like I am pregnant, I'm nauseas, and now my breasts are growing as well. I took a preg. test and it was neg. But with all of my other preg. I didn't test positive until I was four months, plus. I know tubalectamies aren't guaranteed. Could I be preg. or if not what else could be wrong with me?
