When it comes to postpartum depression (PPD) and sleep, it's often a case of "chicken or the egg"—does poor sleep worsen PPD, or does PPD lead to disrupted sleep? The truth is, the postpartum period is a time of massive upheaval: sleep, nutrition, exercise, and overall lifestyle are all affected. Many women feel pressured to return to training quickly to “lose the baby weight,” unknowingly adding stress to an already taxed system.

Stress comes in many forms—overtraining, calorie restriction, and breastfeeding can all compound the body's stress load, impacting both sleep quality and mood. One crucial nutrient that plays a key role here is vitamin B6. Vital for serotonin and melatonin production, B6 needs nearly double during lactation. Low levels—especially due to inflammation—can significantly worsen both mood and sleep.

Supporting your postpartum recovery starts with reducing stressors and ensuring your body is well-nourished. Prioritizing bioavailable sources of B6, like animal proteins, liver, dairy, and seafood, is one step towards better sleep and a more stable mood.

Short answer: yes.
Long answer: it’s complicated.

While mainstream medicine may downplay the impact of stress on fertility, science and biology tell a different story—especially when it comes to chronic, ongoing stress. This kind of stress activates the sympathetic nervous system, diverting vital energy and resources away from reproduction and toward survival.

Chronic stress can disrupt hormone production, delay ovulation, impair implantation, affect egg and sperm quality, and even alter the immune system and gut microbiome—all of which can negatively influence fertility outcomes.

One powerful tool to better understand how stress may be affecting your body is HRV (heart rate variability) tracking. Lower HRV has been linked to lower pregnancy success rates in IVF, highlighting the importance of nervous system health on the fertility journey.

At Kyri Cycles, we’re excited to include HRV tracking in the BBRing, giving women access to more meaningful data and insights to support their fertility and overall wellbeing.

 

When beginning your journey to motherhood, it’s easy to feel overwhelmed by the flood of advice and conflicting information. At Kyri Cycles, we’re all about keeping it simple, grounded, and doable—so here are three powerful steps you can take today to support your fertility. Start tracking your basal body temperature (BBT) to gain deep insight into your cycle, reduce plastic exposure to protect your hormonal health, and tidy up your sleep habits to nourish your egg health. These small but impactful changes can make a meaningful difference on your path to conception.

We grow up being told that pregnancy is a given with any unprotected sex — a message drilled into us during teen sex education. But fast forward to adulthood, and many of us find ourselves facing the frustrating irony: conceiving isn't nearly as easy as we were led to believe. For some, despite normal hormone levels and good test results, pregnancy remains elusive.

This blog dives into three non-hormonal reasons you may be struggling to conceive — from the position of your uterus and cervix, to having sex too often (yes, really!), and even mistiming intercourse altogether. If you’ve been caught in the conception rabbit hole, overwhelmed by acronyms and conflicting advice, this read offers some refreshing, practical insights to consider — and reminds you that understanding your body is everything.

Worried About Low AMH? Here's What You Need to Know

Have you been told you have low AMH and now feel anxious about your fertility — either now or in the future? You’re not alone, and more importantly, you’re not out of options.

AMH (Anti-Mullerian Hormone) is often treated as a make-or-break marker of fertility, but the truth is, it only tells part of the story. AMH is secreted by antral follicles — just one stage in your egg’s 13-month development journey. While it's commonly used to assess ovarian reserve, AMH does not reflect the total number of eggs you have left.

At Kyri Cycles, we believe every woman deserves to understand her body beyond the numbers. Your fertility is complex, dynamic, and far richer than one lab result. Keep reading to gain a clearer, more empowering perspective on your fertility and AMH.

Tired of the constant guessing game around when your period will show up—or if you might be pregnant again? If you have long or irregular cycles, you're not alone. While the pill is often handed out as a quick fix, it only masks the real issue by halting ovulation and creating a withdrawal bleed. But long cycles usually signal a delay in ovulation, not a refusal of your period to arrive. Understanding why ovulation is being delayed—whether it’s due to stress, PCOS, thyroid issues, or low vitamin D—is key to restoring natural cycle rhythm. Tracking your BBT can be a game-changer, helping you pinpoint ovulation and finally take the stress out of not knowing.
