Pregnant after tubal ligation?

[moonandstars75]

I am 34, have had 4 pregnancies, and 3 healthy baby boys.  I had a tubal ligation in December 2008 and since that time my period has been like an egg timer, always a 28 day cycle, always the same length of time (5 days) and always the same symptoms.  My LMP was June 5 and today is July 6 and still no AF.  Last Friday I woke with VERY swollen and sore breasts, as in my bras are barely fitting me.  I have had low cramping off and on over the weekend but still no period.  I am tired and last night while making tacos for my boys I had to run out of the room as the smell made me gag.  I took an Answer HPT this AM and it was a BFN so now I am even more confused.  Has anyone had this happen?  I know the chances of conceiving after a tubal range between 1-2% depending on length of time since the surgery and method used, I just FEEL preggo, after going through 3 full term pregnancies, all my symptoms are the same...am I going insane?

if you are testing negative, you shouldn't have enough hormone in your system to have any symptoms....
