baby fever

So, I'm 17, I turn 18 in August of 2017. I have the worst baby fever ever. I constantly day dream about it and if my boyfriend were to finish inside me, I probably wouldn't care much. I just wish I could try to calm it. I tell myself that I cannot financially care for a baby, and I need to get through school. Anyway, I was wondering if anyone here has tips on how to subdue the baby fever? :/
