I have three kids and after i had the third son in 2005 i got my tubes tied that was 6 years ago now i have been having unprotected sex with my boyfriend and in september 8th 2012 i had my period it was regular but when my peroid went off i was feeling sick to my stomach and was having very bad stomach pains i threw up and then later i was rushed to the hospital for having very sharp pains in my stomach they said it was kidney stones but i really dont believe that then this month i was suppose to have my period this month on the 8th and i missed it. this month i was having constant headaches sleepyness and peeing more at night at least 5 times at night. Not this is the 2nd day that my peroid hasnt came on. I took a test today but the line said neg. but the line was so faint i could bearly see it. What should i do and is it possible that my tubes can be loose after 5 to 10 years?
