My period starts w a day of spotting. 1/2 day of heavy flow, nothing for a day, back to normal flow for a day then spotting for a week. Is this ok?

Perimenopause. or pre-menopause symptoms? Hormonal fluctuations at this age can possibly do this. May need to have your blood fsh, lh , estrogen and progesteron level to be checked if this happens again. Talk to your gyn.
