It's about 2 girls that fall in love with each other, but they feel shame because of all the people that stare and their family. She is confused and can't stop thinking about her, hence the lyrics "all the things she said, running through my head.". And no, neither one of them are pregnant, I don't know how someone could get that from the song, but that's not what it is about.
I agree with most of above. They're actually bi though. Like best friends but not in love. The video's about how they feel their parents are like..homophobes or something and people are staring at them. .
Two girls that love one another and can't stop thinking about each other.
I actually think it's about anorexia. If you look beyond the video to the lyrics I feel like she is talking about being in love with an eating disorder. Hence the part where she says mother looking at me...etc...she is stuck behind the fence of an eating disorder and she can't get out. The video is just for show...
