Are the 'luteal uglies' a real thing?
"Is it just me or am I the ugliest person alive?"a woman in her early 30s asks the camera on TikTok, accompanied by the caption "POV: Girls in their luteal phase."
The video has 2.4 million views and hundreds of comments.
"This is literally me," one woman writes. "I'm angry at how accurate this is," another says.
There are thousands of videos like this one on social media, lamenting the "luteal uglies" - the changes in appearance and mood that women say appear during the luteal phase of their menstrual cycle.
During this phase, which occurs in the second half of a woman's cycle and ends when she gets her period, women experience a huge drop in oestrogen. So are the "luteal uglies" a real thing?
According to Dr Louise Newson, a GP and women's hormones specialist, this change in hormone levels means women can experience a shift in their appearance, sleep and mood during this time.
"Our hormones affect our skin, they affect our collagen, so a lot of people find their skin becomes drier, their complexion not so bright, they might have acne and spots," Newson explains. "They might get bloating and breasts can change shape."
Elena, who works in hospitality and as an actress in London, says she feels lethargic and "completely unmotivated" during her luteal phase.
"I feel like my brain is working in slow motion, I tend to become clumsy and way more forgetful," she says. "I don't want to socialise as much and I feel low."
Newson says that while women are starting to talk more about the impact of their cycles, many still do not know what to do about it.
"These women are genuinely suffering and it's affecting their ability to work, function, socialise and just exist," she says.
The response to women's concerns can also be frustrating, she adds.
"Would you say to a man 'Oh your testosterone is down, just don't go to the gym, have a duvet day?' It's unacceptable that women have to put up with it."
Your relationships may also change during the luteal phase, Newson says - which is something freelance journalistHenrietta experiences.
"If I find myself wanting to get irritated with my wonderful, hilarious, chilled out partner there's an extremely high chance I haven't had my coffee, haven't eaten or that I am in my luteal phase," said the 30-year-old.
It also affects her friendships. "With my friends, I tend to either overshare and regret it, or isolate myself from them and regret it."
More education and discussion about menstrual cycles are needed, says Elena, who only learned about the luteal phase through social media at the age of 24.
O'Neill says there is "so little education that women receive about the fundamental aspects of how their bodies work".
So much so that many women have turned to TikTok for help.
In one video, which has 2.4 million views, a young woman asks: "Ladies, what do you do during your luteal phase to feel better?! I honestly can't cope any more."
There are thousands of comments, with one follower suggesting to "wear baggy clothes and avoid the mirror", and another saying "eat chocolate".
Another writes that the luteal phase makes her "avoid my husband", while someone else says they cope by watching television "with a bottle of wine".
But this advice may actually be detrimental - so what can help women cope with their luteal phase symptoms?
Understanding that it's a "predictable, temporary phase" is important, says O'Neill
Nutrition is key during the luteal phase, she adds - and staying hydrated can help reduce puffiness
Easing off salty foods, reducing alcohol intake, and keeping up movement can all help too
Steering clear of processed foods and alcohol will help you avoid increased inflammation, Newson explains
You should see a health professional if you are particularly struggling during the luteal phase, Newson adds, encouraging women to advocate for themselves
"If people don't get what they think is acceptable in the first, second, third, appointment they should go and see someone else. These symptoms don't usually go on their own," she says.
