“When paparazzi follows you but you’re not even mad cuz you love your look and the chance to show off the leather skirt Jemima lent you and anyway you’ve had your period for 13 days and the inauguration is in 10 so this is the least of your f—— problems,” she wrote.

Alongside the shot she included the hashtag “#bleedforthis.”

In the past Dunham has been open about her painful struggle with endometriosis, a disorder that causes uterine tissue to grow outside the uterus. Its symptoms can include vaginal bleeding, cramps, chronic exhaustion, bloating, possible infertility and severe mood swings.

Though Dunham initially feared people finding out about her diagnosis, she decided to be honest with fans and tell them the truth. She has even said the disorder helped her become more in tune with her body.

“I am strong because of what I’ve dealt with. I am oddly fearless for a wimp with no upper-body strength,” she wrote in the eighth edition of her newsletter Lenny Letter. “And I am no longer scared of my body. In fact, I listen to it when it speaks. I have no choice but to respect what it tells me, to respect the strength of its voice and the truth of my own.”
