Baby before marriage....

I want to see what other people’s views are on this... ever since I was little I always had a mindset for myself that I want to be married / engaged before I have a child. Well here we are I’m with my boyfriend and we are trying to have our first child together. He says we will be engaged by the time the baby comes but something in me can’t let it go that I’m not engaged first. I don’t understand what it is... i see other people who have a baby with their boyfriends and I think it’s fine.. but for me.. I feel a little.. embarrassed? I know my boyfriend is 110% committed to me. This is only our 2nd month TTC and a part of me wants to stop after this month until we’re engaged. Is that wrong of me? Thoughts? I feel guilty both ways I think about it..
