Need advice...

I am 39 weeks and 2 days. My boyfriend and i have been together for 2 years. He in our first year gift me a pre-engagement ring (don't know why he calls it like that) so I was like happy with it. Then I got pregnant and everything has been fine. But now I want to get married cause I feel it's time cause there's a baby on the way. I told him I wanted an engagement ring from wish (most of them cost a dollar) which I found really pretty one. I told him I wanted one and he laughed at my face. Don't get me wrong he loves me and loves our baby. I just asked him if he was laughing at me and he said no. So I stand up and went to my room. I am upset by it but not so much. Just feel like he doesn't want to get married but did wanted to have a baby. Anyone think it's okay? I should not be mad? I just want to do the things the right way that's all. Like fix a bit my future and get married and stuff. People judge a lot if you are not married but have a baby.
