'I always wanted to have three kids, and then I've had some challenges and some miscarriages so I just didn't think it was possible.'

She was also candid about her battle with postpartum depression.

'For me I would just wake up and feel like I was covered in tar and it wasn't the first time I'd experienced depression so I just thought "Oh, well, this feels familiar, I'm depressed, I think,"' she revealed.

Alanis said she waited four months to seek help for the depression, but won't wait that long this time around.

'Now this time I'm going to wait four minutes,' she insisted.

'I have said to my friends, I want you to not necessarily go by the words I'm saying and as best as I can, I'll try to be honest, but I can't personally rely on the degree of honesty if I reference the last two experiences. I snowed a lot of them as I was snowing myself [the last two times].'
