Probably either a blip in your cycle or your hormones changing as you head into perimenopause. There are other issues that can cause long or frequent bleeds, but one event shouldn't be reason to worry.
Having been through irregular bleeding already, I would advise not to worry at the moment unless you are bleeding heavily. My hospital uses "completely soaking a pad per hour" to define heavy bleeding worthy of being seen, but you'll have to judge for yourself if your bleeding is so heavy you think you need an emergency visit. Now, assuming it's not that heavy, I would put in a call to the doctor because if it doesn't let up or happens again, they'll likely want to investigate things before assuming it's the beginnings of menopause. A call or visit now will hopefully have you further along in that process down the road.
Meantime, be sure you're getting plenty of iron in your diet, as these crazy periods can lead to anemia, which strangely can lead to more crazy bleeds.
Have a look under the menu at the top of the page. There's loads of informative menopause stuff there. If you have any questions, feel free to post and ask. We're a friendly bunch!
