Am a mother of two children aged 23 and 19. Till date, have been having unprotected sex and have never conceived after the removal of both my tubes in 1994. From November 2010, have been having irregular period. But after reading all the posts written here, I am not feeling too good as I am not in a position to have another child. Please advice if there is a possibility of getting pregnant when one is possibly heading for menopause.
