Im a 33 year old mother of 5 with my last child ,i decided to have a tubal since all other birth control failed me , but lately i've been naseas, and gagging , ive gotten my period bit its diminished from 7 heavy day to 2 heavy and 2 spotting ,i also been dizzy and bloated at times , im pretty sure im not pregnant ,so any ideas on what it could be ? besides aren't tubals 100% birthcontrol or at least 99.9%
