Pregnant and not with dad

I posted a week ago that I found out I was pregnant and I wasn’t with my ex bf.

I have found out yesterday that I am 6 Weeks and 5 days pregnant. My ex bf met me there and we had my ultra sound done.

He said he has nothing to say to me, he didn’t speak to me at all the whole time.

He is also seeing a new girl.

We been broken up for 4 weeks.

I don’t know what to do.

2 days ago he said he will do anything to get custody of this child and make my life hell.. is what he said to me. He said I’m a fuck head and he doesn’t want this kid but he will try take it off me.

I don’t know what to do :(
