Does anyone else feel like this?

I'm posting anonymously because I know this is weird. 
I feel like I am obsessed with getting pregnant. My SO and I are NOT ttc, at all. It's all I can think about though. All I'm thinking about it being pregnant, not the actual baby. Like I'm in love with the idea of being pregnant, but I don't really want a baby. I know this is crazy but I can't help what i feel. Is there something wrong with me?
