I had my tubal ligation a few months after you(May 05) and have also been experiencing these same symptoms! I haven't thought I was pregnant though. My GYN said that it is common after the surgery for period symptoms to get worse and come earlier in the cycle. I am considering having surgery to stop my periods all together because I am SOOOO SICK of dealing with this every month. On top of all of the early symptoms I'm also having very heavy periods! Last week I couldn't even leave the house because I was in the bathroom every hour. You should talk to your doctor, maybe there's something he or she can do to help easy the situation for you. I'm sure you feel the same way I do, my period is taking over my life! Good luck!
