I used to have very regular periods up till age ot 31 and gradually started having irregular periods. sometimes I would miss a month, and then 2 months. the last stint was 5 months of no period. This is excluding when I was breastfeeding so when I should be having regular periods. my weight has been stable and stress level is obviously more up since I have children now! If you could post your experience and share with me, that would be lovely.
