I am 45 yrs old soon to be 46, at age 30 I delivered my 4th child, had a tubeligation,(burned and cut), had laperoscopy at age 37 was told tubes not repairable. with new sex partner now about 7 months, almost immediatly into relationship started having irregular periods. but generally always 21 to 28 days apart generaly light to moderate and this month I have not had any. I have all the classic symtoms of pregnancy mostly swollen, sore breasts. heartburn, nausea ect. could I accually be pregnant or should I be concerned more about menopause and does it usually start so suddenly?
