How Perimenopause Affects Your Period

We hear a lot about menopause and the way it impacts the female body, but there’s less talk about what happens beforehand—menopause doesn’t just come out of nowhere, after all. There’s a name for the gradual road towards menopause, and it’s called perimenopause. Perimenopause is essentially a transition into menopause during which the ovaries begin to produce less estrogen. It usually sets in when a women is in her mid-forties, but can start as early as the thirties or even twenties in some cases.

Most of the time, perimenopause tends to last around three or four years, but it’s duration can be shorter or longer depending on the individual. One of the most notable symptoms you can expect to experience during this time is a changing menstrual period. For that reason, we’re going to fill you in on all the period-related changes you might encounter during this transitional life phase. To learn more about other changes during this time, we have another blog post on perimenopause has helpful information. Read it here.

Due to changing hormone levels and unpredictable ovulation, you can expect to experience some period irregularity during perimenopause. These changes run the gamut—you might skip a few periods, see spotting between periods, experience menstrual flows that are heavier or lighter than usual, or even those that last longer or shorter than you’re used to. Most of the time, you don’t need to be alarmed by these changes, as they’re common even among women who have experienced extremely regular periods for their whole lives. If two months or more pass by and you haven’t had a period at all, you’re probably in the later phases of perimenopause.

One thing to understand about how menopause affects the menstrual cycle is that it’s rarely the same from woman to woman. Some women don’t experience any intense symptoms, while others are greatly affected by things like heavy bleeding. Some women will experience inconsistent periods for months or years, whereas others see their menstruation end more suddenly.

During this time of period irregularity, your fertility will likely decrease, but it’s important to remember that as long as you’re still having your period, you can still get pregnant. If you’re using birth control to prevent pregnancy, you’ll want to keep doing so until you haven’t had your period for 12 months in a row. Once you hit this 12 month mark without a period, you’ve likely moved from perimenopause into menopause.

On a similar note, the irregularity of the menstrual cycle during perimenopause can bring changes like extreme hormonal shifts that can be hard to deal with. To regulate the menstrual flow, some women take low-dose hormonal birth control pills up until menopause. It’s smart to keep communication open with your doctor and fill them in on any atypical changes that arise during perimenopause. Things like heavy bleeding and spotting can be normal in perimenopause, but they can also happen when something else is going on in your body, so it’s always a good idea to tell your doctor what’s going on with your body.
