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.
