Help me understand

Hey ladies, my boyfriend and I were having a recent discussion... he thinks I’m preggo which I’m not I’m on mirena bc but we already have a 9 month old daughter together. Well in our text messages he says if it happens it happens (if I was pregnant) & idc it you were pregnant also I think you’re pregnant you sound pregnant so I respond : it sounds like you want me to be.... ladies what does he mean by if it happens it happens or I don’t care if you were pregnant does that mean he wants a baby or not ???update : I took a test and it’s negative but he still thinks I am pregnant because of my dream about fish last night
