Why you might have a higher libido during your period

A higher libido during your period is common, and it usually traces back to where your hormones sit in these first few days. Estrogen and progesterone both drop to their lowest point right as bleeding starts, which is part of what triggers the bleed in the first place. Testosterone doesn't fall nearly as much, so its relative influence on desire can feel stronger once the other two hormones step back.

Testosterone plays a real role in sexual desire in women, even at the small amounts your ovaries and adrenal glands make. A 2015 randomized trial published in Contraception tested whether adding a testosterone-restoring supplement (DHEA) changed mood and sexual function in women on a combined birth control pill. The supplement produced small improvements on some mood measures, but premenstrual arousal scores were actually better with placebo, and overall sexual function scores didn't differ significantly between groups. That mixed result, no sexual-function benefit, and a premenstrual arousal score that actually favored placebo, shows the testosterone-desire link isn't as simple as more testosterone meaning more desire, even at these small amounts.

There's a practical side too. Once your period starts, the cramping and bloating that built up beforehand usually start to ease. Less physical discomfort, and no more guessing about when your period will arrive, can simply leave more room to feel interested in sex again.

Yes. Desire naturally varies across your cycle, and feeling more interested in sex during your period is just one normal pattern among several. Some women notice the opposite: cramping, bloating, or the hassle of managing a period lowers interest instead. Both reactions fit within a normal range.

Desire during the follicular phase, which starts the day your period begins, is shaped by rising estrogen as a new egg starts developing. For some women that rise starts fast enough to overlap with the last day or two of bleeding, which is part of why desire can climb while you're still on your period. For others, the shift shows up a few days later, once bleeding has fully stopped.

If you want to compare what you feel during your period with what happens earlier in your cycle, libido changes before your period walks through the premenstrual pattern, and libido changes in the luteal phase covers the two weeks before that.

For most women, a higher sex drive during their period settles back toward baseline within the first week, often by the time bleeding stops. Estrogen is already climbing by days three to five of a typical cycle, and once it reaches a certain point, desire tends to track with ovulation instead, often peaking again closer to midcycle.

How long it lasts for you depends on your own cycle length and how your body responds to the hormone shift. A short period with light bleeding might mean the whole window passes in two or three days. A longer, heavier one can stretch that window out, partly because cramping and fatigue are still competing for your attention.

There's no single timeline that applies to everyone, so paying attention to your own pattern over a cycle or two tells you more than any average would.

Not directly. PMS is the mix of physical and emotional symptoms that shows up in the one to two weeks before your period and eases once bleeding starts. PMDD is a diagnosis that needs at least five symptoms, including a mood symptom like irritability or low mood, in that same final week, confirmed by daily tracking over at least two cycles. Both are about the time before your period, not during it.

What PMS can do is shape how you feel about sex leading up to your period, which colors how welcome a rise in desire feels once bleeding starts. A 2017 cohort study in the Journal of Sex & Marital Therapy found that women with PMS reported sexual difficulties far more often than women without it (77.6% versus 27.3%), along with more sexual distress (51.7% versus 24.5%). That study measured problems with desire and arousal, not a rise in either, but it shows how closely PMS and sexual function can be tied for some women.

If your desire swings hard, from barely there before your period to intense once it arrives, that contrast on its own doesn't point to PMS or PMDD. It's worth noticing if it happens alongside other symptoms, though.

None of this needs fixing, but a few things make it easier to act on if you want to.

• Keep a dark towel down, or have sex in the shower, if mess is the main thing stopping you.
• A menstrual cup or disc, worn correctly, can make penetrative sex less messy during your period.
• Use lubricant if bleeding is light enough that you feel drier than usual, since tissue sensitivity can shift through the cycle.
• If cramping is part of what's distracting you, treating that first, with heat or whatever has worked before, can clear the way.

Niyora is a PMS and PMDD support app. If you want to see whether this shift lines up with where you actually are in your cycle, rather than guessing, its estimated PMS window gives you a rough read on your timing, so you can watch the pattern instead of wondering.

Most shifts in desire across your cycle don't need medical attention. See a GP or gynecologist if sex is painful at any point in your cycle, if bleeding is unusually heavy or lasts longer than seven days, or if swings in desire are causing real strain in a relationship or in how you feel about yourself.

It's also worth a visit if changes in libido show up alongside symptoms that take a week of every month and ease only once your period starts, since that pattern fits PMS, and sometimes PMDD. Bring two months of daily notes on what you notice and when, so your doctor has something concrete to work from, rather than a memory of a hard week.
