I used to be on a regular 28-29 day cycle, until after my second child (4yrs ago). It now varies between 22 and 30 days, which for many people might not be much, but for me it is very different. I am late 30's now, so it tstarted in my mid 30's - could i be the start of menopause? Should I see a GP or it it 'normal'? Is there anything I can do to make them more regular? Ta.
