She added that she 'had some complications early on,' and completed 'a decent second trimester' but was aching at the 25-week mark.
'I feel like I was woefully ill prepared cuz I dunno if pregnancy is as visible or discussed as it should be,' she said. 'I just didn’t [really] understand what I was getting into.'
In March, she said to Rolling Stone of her romance with the SpaceX innovator, which began two years ago this month: 'I do actually just really love my boyfriend.'
In the chat with the publication, the Canadian beauty said that she 'just did not understand what I was getting into at all' in dating the famous businessman.
'No one believes me about this,' she said. 'Not that I’m mad about it. I just didn’t think it would be a thing. The s*** that’s happened with my boyfriend this year has overwritten so much of my life’s work.'
Grimes in February said she wants to let her baby choose their own gender identity.
When asked whether she's expecting a boy or a girl during a YouTube live stream (which has since been made private), the musical artist said, 'I don't want to say the gender of the baby ... because I feel like their privacy should be protected.
'I don't think they can consent to being famous or being in public.'
Grimes also revealed she doesn't want to 'gender' her baby, saying they can "decide their fate and identity' on their own accord.
'I don't want to gender them in case that's not how they feel in their life,' she said. 'I don't know, I just feel like it doesn't need to be known ... They may decide their fate and identity.'
