I am 44 years old, I have 2 adult children and after my youngest was born 19 yrs ago after a C-section, they did a tubal ligation....lately I've been feeling really off....I mean for the past 1-2 months have been extremely nauseous, fatigue, dizzy and lightheaded I recently took 2 pregnancy test, both of which came back negative. Is pregnancy even possible? I'm so worried that I made an appointment to see the specialist. But is it even possible after 19 years?
