Am I wrong?

Hi, I'm 34 yo and 6 weeks pregnant, after 5 years of trying , a MS and an ectopic pregnancy. We've been trying for so long, I cried so bad when I found out, tears of joy and fear of loss. But now I feel terrible, I am scared that I am not going to be a good mother and my husband a good father, I'm like what did I do, why am I messing up my life like this and all these crazy thoughts. I also feel guilty cause I'm thinking this way, and I'm afraid of an other miscarriage. I am so confused.. Please help.
