Fiancé is so angry about us being pregnant

Fiancé isn't happy we're pregnant because we lost our daughter at 20 weeks 4 months ago and he said he's not ready. When I asked him to take me to my 12 week ultrasound he got angry and said he shouldn't have to miss out on money and that he doesn't care or want the baby continuing to say he wanted a abortion and that it's my fault we're pregnant because I didn't prevent it and I wanted sex... which I think is extremely rude considering he's the one that constantly came in me and I would tell him to be careful and he knew I wasn't on any birth control because I was advised for my body to go back to normal plus having sex was consensual not just me wanting it so this blame game is really immature and unfair. He's saying when the baby comes he won't be happy about and doesn't want to be apart of this pregnancy. I'm really hurt and need advice on wether he'll come around or I just completely should do this by myself... he was so happy about our last baby and now he's just so angry we are pregnant again and doesn't want to take any responsibility for his part in this.

Edit: I will just add that at the beginning we had a very serious conversation about it and he said he would be supportive but his mood completely changed and basically just overall being rude to me all together so I'm even staying with my parents ATM. The only reason I'm considering leaving is because he's being so inconsiderate about the whole situation and making me feel even worse about it. I'm not over losing my baby girl either but that doesn't mean I'm just going to hate this baby because I wasn't ready for it to happen this soon. I knew the risks and so did he but blaming it all on me is just pathetic.
