How do you know your in perimenopause? Im 44, had a baby last March and my cycles rangefrom 26-32 days, usuallyits 28-30. Im now 6 days late and on cycle day 34, 35 in 2 hrs. Ive been late by 2 or 3 days before in the past 6 months but i just had a baby. I feel something going on, sort of like period is coming but feels differently, feels heavy. I dont have the typical perimenopausesymptoms but could this be the start? Confused and scared to test really.
