Need opinions!

I just found out I’m 6 weeks pregnant. I’m 21 and he’s 28, and we’ve been together a little over 2 years. I told him as soon as I found out and because we weren’t really trying, he was shocked and upset. He has made it clear he doesn’t want any kids right now because he still wants to go back to school and get settled in life. I wasn’t necessarily wanting a kid right now but now that I’m pregnant, idk. I feel very mature for my age and I know the person I am, I wouldn’t be doubting becoming a mother at all. I don’t think we’ll break up if I decide to keep the baby, but I really think he will be unhappy, but he said he’d be there for the kid no matter what happens. A part of me wants to have an abortion because that’s what he wants and it’s not the perfect time for either of us to have a kid, but another part of me thinks I’ll really regret it because I’ve struggled with depression and anxiety about being infertile for a very long time. I’m just really torn about what decision to make and I know ultimately it’s up to me but I just need different opinions because I haven’t told any of my friends or family. Thank you in advance.
