I keep forgetting I'm pregnant πŸ™ˆ

Ok so I know this is crazy and I don't know if I'm the only one. I'm 14 weeks and so far everything is fine and dandy. But sometimes I do stupid things without thinking I'm pregnant. For example I bend over real fast to pick something up the other day and felt like a huge pressure in my belly. Omg I felt so bad! Or I'll pick up something real heavy or generally do things I should be more aware of now. I can't feel baby yet so I guess sometimes it's like the pregnancy is a dream. I keep forgetting or maybe just not believing there's a baby in there!!!! What do/did you do to help yourself believe you have a child in your belly before actually feeling the baby move?
