Would it be wrong?

So back in July I had found out I was pregnant and my fiance and his father told me I had to get an abortion. I eventually agreed and went through with it but after I felt like I did something very wrong and still do. Since then we've been using condoms and I was on birth control until I lost my insurance but if it ever came down to it and I did get pregnant again before we planned should I keep it from him until it's too late to get an abortion or would that be wrong???
