I keep buying baby stuff

My fiance and I have been TTC for 2 years now, and we finally went to the fertility clinic, I'll be going on clomid, and the person there said that with clomid I should be pregnant within 4 months (fingers crossed). I started buying baby clothes a long time ago (mostly gender neutral), and I have a high chair and I'm not even pregnant yet, am I crazy for already buying stuff?
