Should I?

So back story, my and my boyfriend were together and he kept bringing up his wants me to have his child. I have a daughter from a previous relationship. I told him I didn’t want another right now... so he got me pregnant on purpose then when I found out I was pregnant he changed... told me to kill the baby, he even tried to make me miscarry. I haven’t spoken to him since. It’s been 3 months... ( I’m 3 months pregnant) I got an ultrasound today and really want to show him but I don’t want him to see and start wishing bad on our baby. What’s your opinion?
