Speaking on 'The Drew Barrymore Show', she explained: "I was eight months pregnant and it was my fourthbaby. This time around I had massive headaches that completely put me down.

"I was in bed and I couldn't hear or see anything. I had a hot bottle on my head and was just like this [lays back] all day, 24 hours.

"And it just got worse and worse and worse and I saw different doctors and neurologists and they said, 'It's probably a nasty migraine...'

"None of the doctors sent me to get an MRI, even if we asked for it before.

"If I had gone through a spontaneous delivery, I would not have been here.

"It was all of this [touches head], 15 centimeters and five centimeters, three different ones. And it was the first time that I felt what it meant to be scared to death. And again, had I known better, they could have just put me on blood thinners and done."

She said: "Three out of 100,000 pregnant women will have a brain clot. But if you feel any symptoms just check yourself.

"MRI is very easy and there's no radiation or anything."
