Abortion 4 months ago now want baby

My now fiance and I started dating in June and we took our first vacation to Vegas in Sept during which time I got pregnant. I was still unsure if the relationship would work and how I felt.. I freaked out and couldn't handle it. Although he did not agree with my decision he was very supportive I was 6 wks and 6 days when I went through with it. I didn't let him come with me because it was hard enough but when I got home all he did was worry if I was OK. At that moment I knew I made a huge mistake and he was the right man. Now we are engaged and I want to get pregnant am I wrong for that?
