I had to fill my vagina with ultrasound gel yesterday for an MRI... I had no idea this was a protocol for measuring endometriosis! how cool It's a technique called vaginal opacification... the vagina is normally a collapsed space, and on an MRI, collapsed walls are hard to tell apart from the tissues right next to them When you fill the space with gel, it distends the walls and separates the structures so the radiologist can see the boundaries better One of the hardest places to detect deep infiltrating endometriosis is the area behind your uterus. Lesions there are small, fibrotic, and often missed The gel shows up as a bright signal on the images, so any lesion pressing into or growing through the vaginal wall appears as a dark nodule against that bright background Endo affects 1 in 10 women, usually takes 7 years to diagnose, and traditionally requires surgery for diagnosis.... this MRI protocol is an alternative route for detecting deep endo

🚨 my hormones just did something unexpected... They are usually more erratic... but last menstrual cycle my daily hormones seemed ‘calmer’... + daily estrogen swings ~35% less + daily progesterone swings ~30% less + cycle length shortened What’s going on? First, my cycles have never been regular. Over the past 18 months, they ranged from 31 to 68 days. And the hormones underneath were noisy: + would regularly max out my tests + big repeated spikes + multiple waves per cycle But then I changed my lifestyle dramatically overnight… I just did 40 days of perfect consistency: + same food + same bedtime + same workouts + no alcohol + 8.5 hrs sleep every night + same hydration + NO cheat days + NO deviations Here’s how that affected my results... My latest cycle: + 34 days long + clean LH surge + estrogen rose once + progesterone rose on schedule + 35% smaller swing than last year … and ovulation around day 24, versus my historical average of day 29 It was my most ‘normal’-looking cycle ever. Why would this happen? Keep in mind… I’ve been incredibly overwhelmed, stressed, and busy while starting this new protocol to become the world’s most measured woman. Here are some theories... 1/ Consistency. Your cycle is run by your hypothalamus. It’s a region of your brain that also monitors your stress, your sleep, and your food supply. And we know unstable schedules disrupt cycles… A meta-analysis of 14 studies found that women working rotating shifts have 35% higher odds of irregular cycles than women on fixed schedules… and for women under 30, it's 66% higher. My protocol locked sleep, food, and my schedule down to the minute. Maybe my hypothalamus finally got a quiet room? 2/ Coincidence. Erratic cycles are sometimes followed by calm ones. One cycle proves nothing. I am very curious to see what my next cycle is like… 3/ Cleaner measurement. I test my hormones via urine, and urine concentration moves with hydration. In the last 40 days, my water intake and test times have been steady every day… so part of the "calm" may be that my measurements got steadier, not just my hormones. Two things this can't explain: my LH stopped spiking for days at a time, and my cycle length shortened. 4/ Something else? It could be something we haven't thought of yet… That's why we measure and get repeat measurements. -- If theory #1# is real, it matters far beyond me. An estimated 14-25% of women of reproductive age have irregular cycles. The standard responses are wait and see… or hormonal birth control. If consistent sleep, meals, and routine measurably stabilize cycles… the first thing to try would be free. My next cycle will give us clues… I'm already 7 days in. If you're new here: I am becoming the world's most measured woman… collecting 14 million data points across my menstrual cycles, because female health is desperately understudied. We’ll post all results here (good and bad, wins and failures) with you for free.... sharing everything we find.

If you're a female… …with high cholesterol …in your 30s …you may be misdiagnosed In one study, ~6% of women were labeled with high cholesterol… when they were tested again later in their cycle, their results came back ‘normal’. Your cholesterol can swing by 19% depending on the day you get your blood drawn. + First half of cycle = higher. + Second half of cycle = lower. Your cholesterol isn't one number. It moves monthly with your hormones. In the first half of your cycle, your cholesterol reads high. After ovulation, it falls, hitting its lowest right before your period starts. When I found this out, I was shocked. Why does no one know this? The answer took me down a rabbit hole. When your blood lab results come back, there's a "normal range" printed next to each number. That range is created by measuring a big group of people, and calling the middle 'normal.' But for decades of blood draws, cycle days weren’t recorded… so their cholesterol variation was invisible. Then, it got worse in 1977 when the FDA excluded women of childbearing age from early drug trials for 16 years. So it wasn’t until 2010 when the first rigorous, large-scale proof came back that cholesterol changes with the cycle. A female health study looked at blood biomarkers and compared them with cycle data. It took 60 years to figure that out. And yet, it's 2026, another 16 years later, and the reference ranges are still outdated. So… why hasn't this been fixed? Heres 7 reasons why... #1#. Most doctors don't know. It is not in their training or guidelines. #2#. The lab companies haven't built for it. There's nothing stopping Quest or LabCorp from adding this. They set their own systems… they just haven't prioritized it. The individual who takes your blood has nowhere to note what cycle day you’re on. #3#. Self-reported Cycle days. Most women were never taught to track their cycles. The education is thin, and full of myths (most women don’t ovulate on day 14). Even a woman who tracks carefully may have imperfect information. For example, ovulation shifts month to month, and sometimes it’s skipped. #4#. Cycle phase confirmation. Cycle phase can be confirmed with a blood or urine hormone measurement alongside the draw. It's just that nobody has added this step. #5#. The starter data already exists. The 2010 study measured hormones and cholesterol across hundreds of women's cycles. That's enough to build a first version of phase-specific ranges. Validating it at scale would take more data, but collecting it is now trivially cheap. #6#. We repeat the test, but still ignore the cycle. Cholesterol is often checked more than once, which can help smooth out biological variation. But those repeat tests usually aren't timed to the menstrual cycle. #7#. Ranges only change when someone decides to change them. There's no central body that sets reference ranges… each lab company adopts and verifies its own. When pediatric ranges turned out to be wrong, a research group rebuilt them from thousands of healthy kids and labs adopted the results. The same thing could be done here. It’s just that no one has started. The data to fix this is completely collectible. A third of American women already track their cycles on their phones.…. and the biobanks have millions of cholesterol results. Nobody has put the two halves together. Insanely… cholesterol is not the only marker that varies across your cycle. In one study, about 50% of the molecules measured in women’s blood and urine moved with the cycle. And yet… it's still almost entirely unknown. So I am running my own experiment. I'm collecting 14 million data points on my menstrual cycle… my brain, blood, skin, saliva, grip strength, etc. We’re spending $2.6 million on this. And every second of my day is monitored and accounted for. This will be the most quantified menstrual cycle ever. We’ll post all results here (good and bad, wins and failures) with you for free.... sharing all the practical insights. My hope is that we can put words and numbers to the female experience.
