"By very lucky chance, my doctor who I've seen for the better part of a decade, she is a queer woman. So I asked her, 'How should Hannah and I enter this world of attempting to have a baby?' " Bernard recalled.

"And my doctor said, 'I honestly think you and Hannah, however you decide, should get some sperm and try to have sex at home, the way a lot of the world does it," she continued. "I would recommend you seeing if that works before you do any fertility stuff, because it could be really fruitful.' "

Bernard explained they "were able to get pregnant at home," adding: "We feel so lucky. We know that this is not the norm, that many couples struggle with fertility issues. Queer or hetero, it doesn't matter.

"And so we just feel so lucky that this worked and that we were able to do it in a non-clinical setting, which was truly so special for us," added Bernard.
