Im 42 years old and had my 5th child by C-section 4 years ago at which time I had a tubal ligation also. Since then my periods have been regular up until about 6 months ago when they became erratic and unpredictable and now I haven't had a period in like 2 months. Lately I feel like my abdomen is swollen and is a little tender but when I push on it I can't feel anything but I know its possible I might not be able to feel a tumor if there is one. I also feel a little nauseous and light headed. I'm so scared that it could be cancer that Im shaking all the time, Doctor can't see me for another Month :( Can anyone give advice?
