So lost right now

I’ve just found out I’m 5 weeks pregnant but I only had a baby 3 months ago. I haven’t spoke with my partner yet but I think he is going to want to terminate. But I just don’t know what I want and if I could go through with it if it is what I wanted. They won’t even be a year apart my due date is 1 month before my first was born. I am only 20 and my partner is 22 and already has a two year old. 😩😩
