How to Choose a Midwife

How to Choose a Midwife

1 day ago
Choosing the right midwife is a pivotal step in creating an empowering birth experience that aligns with your values and preferences. Midwives, including Certified Nurse-Midwives (CNMs), Certified Midwives (CMs), Licensed Midwives (LMs), and Direct Entry Midwives, provide crucial prenatal, delivery, and postpartum care. To find the best fit, it’s essential to interview potential midwives, focusing on their philosophy, approach to interventions, experience with complications, and support for families. Asking key questions about certifications, availability, and policies on pain relief and episiotomies can help ensure a positive experience. With careful research and open communication, you can select a midwife who supports your unique journey into parenthood.

The Pink Tax: The Hidden Costs for Feminine/Non-Binary People

The Pink Tax

9 days ago
The pink tax is an unjust pricing phenomenon where products and services marketed towards women and non-binary individuals are often more expensive than comparable items for men, despite no significant differences in quality or functionality. This practice not only burdens women with higher costs but exacerbates the existing gender wage gap, leaving many struggling to achieve financial stability. Over time, these hidden costs can lead to reduced disposable income, delayed retirement savings, and increased vulnerability to poverty. The pink tax also perpetuates harmful gender stereotypes and beauty standards, limiting personal and professional opportunities. Tackling this issue requires informed consumer practices, advocacy for fair pricing, and support for organizations promoting gender equality to foster economic fairness and empowerment for all.

The Invention of the Menstrual Cup

The Invention of the Menstrual Cup

The menstrual cup has transformed period management, offering a comfortable, effective, and eco-friendly alternative to traditional products. Originally created in the 1930s by Dr. Earle Haas as a solution to the limitations of menstrual products, the cup has evolved from its early rubber design to today’s high-quality, medical-grade silicone models. With growing awareness about sustainability, reusable menstrual cups have become increasingly popular since the 2000s, offering up to 12 hours of leak-free protection. This innovation has empowered individuals to experience a more convenient, cost-effective, and environmentally friendly approach to menstrual hygiene.

Testimonials

Michelle H.

Second pair I've bought! It did not fail me this time either. I did not feel gross wearing them at work and honestly hate having to put on a pad to wash them. These are awesome. They shipped them the same day I bought them and I will be buying a third pair whenever I can!

Shasha M.

I have nothing but good things to say. now I have several versions form Heralogie and cannot decide which I like best. The bikini is sexy but for tight pants would recommend a full panty which will not show

Andrea M.

These underwear are amazing! I have a heavy flow and these are truly magical. I wore them just as is and did not have to think about staining or changing a pad/tampon. If you are interested in sustainable period care, get them now!!!

Karissa W.

I've been looking for period undies for a while, and these are so worth it! These look the same and seem to work the same as the most popular period underwear brand. The price on these are a huge bonus, I hate how other brands increase price based on absorbency. I love the inclusivity, too!
