hi could be its just a hic-cup in your system it happens and you have your tubes tired and yes they do come untied. so the only thing you can do is doctor and get tested just to clear the air its the only real way your find out. ok good luck
missed period. i had my tubes tied over 3 years ago since then my "p" have been very normal well on sep 4th started my "p" and withend a few hours had sex with my b. f of many years and after we were done my "p" just stopped no nothing after that till the 12th then had very light bleeding but once again for only few hours this time didn't have sex tho but after a few hours it also just stop no nothing so don't know if i should be worried since normally i know about when i'm gonna start could i be pregnant
