Jessie J hasn't given up on her dreams of motherhood, despite being told she's infertile.

The musician, who revealed her diagnosis on stage during a performance at Royal Albert Hall in London last week, opened up about her situation on Instagram on Saturday. In an emotional series of nots, she explained that she "will be a mother" someday.

"After explaining the meaning of my song 'Four Letter Word' on stage during this tour. The love and support I have received have been overwhelming. Thank you," the 30-year-old wrote. "I was told 4 years ago I won't be able to have children. I was also told I would need a hysterectomy immediately and to be put on medication."

Jessie went on to say that she opted not to take her doctor's advice to undergo a hysterectomy, a procedure in which the uterus is removed, and is no longer taking medication.

"I refused the hysterectomy and I'm off all medication through natural medicine and diet change. I haven't given up hope. I am doing all I can to make it happen the best way my body will allow."

The British pop star noted that "millions of women go through a tough and emotional journey to motherhood," adding that it's "something that needs to be spoken about openly."

"It's taken me a long time to be open. It's my truth. And when I put it in my music it's out there. My journey is just one in millions that exist. I stand with you ladies. Strong in our emotional pain. To turn it into joy."

The "Domino" singer first opened up about her fertility struggles on November 13, during a concert.

"I don't tell you guys for sympathy because I'm one of millions of women and men that have gone through this and will go through this," she said.

"It can't be something that defines us but I wanted to write this song for myself in my moment of pain and sadness but also to give myself joy, to give other people something that they can listen to in that moment when it gets really hard," Jessie continued. "So if you've ever experienced anything with this or have seen somebody else go through it or have lost a child, then please know you're not along in your pain and I'm thinking of you when I sing ["Four Letter Word"]."

Her rumored boyfriend, Channing Tatum, was in the audience during the raw performance.  He seemingly confirmed their romance, sharing a snap from the event on Instagram, praising Jessie for her honesty.
