I met my husband almost (Removed) years ago but we married muta. Our muta has ended but I’m pregnant now and we still sleep with each other I wanted to know is this considered halal? Do we have to renew or how does it work

It is haram.
He is not your husband any more.
You have to renew the marriage, by either permanent or temporary (mutaa) nikah. Sleeping together without marriage contract is zina.
