Baby fever?

So me and my boyfriend just went through a pregnancy scare I was terrified of the thought but at the same time I secretly wished I was pregnant. I dont know what it is. I'm not going to try for a baby in no way. I know very well this is the wrong time for a baby. I know i need to finish school first but I can't help but think about having a baby now. I don't know what to do. I don't want to feel like this because I know in reality I couldn't possibly afford to support a baby right now. I know how much work babies are from taking care of my nephew 24/7 for a week at a time. And honestly I love every second of it even when I'm exhausted. I just wish I was older done with school and married so I could start trying for a baby. But trust me I won't start trying until all of those things happen. I just wish I could shake this feeling.
