Everything is possible,by now home pregnnacy test could give you an accurate reading do one !:)
Well yes, it is possible, although with a vasectomy somewhat unlikely. They have been known to fail though. I second niso's comment. Try a home pregnancy test, it's the only way to know for certain. Good luck.
More likely to be the start of menopause...but sometimes vasectomies do fail.
iam 47 and i had a procedure done called fibroid obleg ion thats where they put these mico beads in to the blood vessels going to the fibroid to shrink them that was 2 yrs ago . my doctor wanted me to go on birth controll i refused i said whatever happens happens iam engaged to a wonderful man who doesnt mind another child this would be my first. since the surgery i have had very light periods and never missed a period . now iam 3 days late and i had a dream that i was pregnant and could feel everything , maybe its just me i kinda think iam pulling at straws. i have 3 foster kids and that cool but ive always wanted my own i hope this is it and my dreams are comming true if not thats life
