The writer and actress, 32, said she sometimes worries she does not think about having children as much as she should.
However Coel, best known for her hit BBC series I May Destroy You, said she had considered adoption.
The London-born actress was in conversation with US actor and rapper Donald Glover for GQ magazine.
She said: “And sometimes I worry that I don’t (think about having children) as much as I should, which is why, just in case I ever think about this more, I’m freezing my eggs, just in case.
“I’ve never been too thinky about bearing my own children through my vagina. I have thought about adopting. That I’ve thought of more than vaginal children.
“But in case I changed my mind, because I don’t know, they say it happens… Like, you reach this point where suddenly you really want babies and all you can think about is you want a baby and the clock’s ticking.
“I don’t ever have that. I’ve never felt it. I’ve never even said, ‘I want to have a baby,’ ever in my life. So I’m freezing them in case that hits me later.”
Following on from the success of I May Destroy You, Coel said she had decided to take September off work.
She added: “I’m asked this question and I have an answer that I give, which is, ‘I’m taking a break.’ However, it’s been a while now.
“And even though I’m still technically working, because, hey, we’re doing press, there is, like, there’s a tiny seed far away.
“I’m just on the edges. I don’t know. I have something in my womb.
“I sometimes equate my show with children. So the inception might be beginning.
“There’s something, but for now, I’m trying to just live for a minute. I think I’ve given myself September to just live.”
