Is it wrong that I want a kid?

I always knew I wanted a kid. Except I have a plan that I want to throw down the drain. (Im 17. Birthday in July.) I had a 10 year plan I made in June. Get my masters. Then work. So you can afford a kid. Then child is allowed. But then I fell in love with my boyfriend in October. Then I met his baby sistet in January and helped him build her nee bed. And ohmygod she loves me. And then he told me "You're such a mom. Give her to me." And then in February he showed me a video of a girl surprising her s/o a pregnancy test. And he actually cried. He said he cries everytime. Told me to surprise him like that one day. And ohmygod. I tried to fight this baby fever. But I want a little human with him. It huurrts. My ovaries. Im glad im getting an iud. 5 years. No child for 5 years starting when I start college. That should be good. Ugh I want one so bad I dont want to get an iud. But no iud is stupid. If I get pregnant in college. My education is ruined. I want to be able to not struggle financially. Its a constant battle in my mind. A war between my uterus and my brain. Babies😭 What is wrong with me?
