getting baby things when not yet pregnant

Lizzie • PCOS, trying for #2
Me and my partner have been TTC for almost 2 years and today I picked up an expensive car seat for free (£100) I've given it a good clean and washed the covers etc and it will be put in out loft until the time comes. My SO thinks I'm weird for getting it considering I'm not yet pregnant and I don't think I will be for a few months. 
Am I strange? I just wanted to be prepared 😬
