Hello, I am 40 years old. I stopped taking the pill 6 months ago and since then my menstrual cycle has been varied from 27 days to 36 days, each flows lasting 4 days. My period is now 9 days late and for the past couple of days have experienced very severe cramping, at night and in the afternoon, have no pregancy symptoms apart from slightly sore breasts. Had unprotected sex once last month. Am I pregnant? or starting the menopause??
