Heartbroken :(.

So 2 days ago I found out I'm pregnant and suddenly my fiance had a change of heart and don't wanna keep the baby, and he's dead serious. 
He litteraly made me pick up the phone and call my doctor to get an abortion, and while I spoke to them they told the me earliest I could come in was 9th may at 11:30, and he started to freak out saying that I need to get it ''fixed'' much sooner than that.
I have not had a single control and this would be my first I didn't tell my doctor I wanted an abortion because I want to see my baby before I make a decision.. 
I do NOT want an abortion I do WANT to keep this baby.
My Gyno confirmed that I have a weird shaped uterus and I would have difficulties concieving when I was on a routine control last year.. Let alone maybe impossible..
We been together for 8 years so this is a shock for me as it was planned..
Should I have the baby ( I know I probably will) and lose him because he threatend to leave me, or should I not be selfish and do as he wants because I would never wanna feel that I forced someone to become a parent 😪
