Is it wrong of me?

I just had a natural miscarriage on July 30th . I want to get pregnant as soon as possible if that's what is meant to be. I live with my brother because he needs to me watch his daughter (he pays me daily)  because her mother is in and out. Recently she's back, probably gonna leave again but whatever. I finally decided to get my own job and do my own thing since this is an on and off thing with the mother of his child. My brother was kind of hurt about the miscarriage I guess. Idk if he really wanted me to have it based off what he told me after it happened. I had just left the hospital as they told me my baby stopped growing at 8 weeks and at that point I was 11. My baby didn't even pass yet and the first thing my brother says to me as I walk in the door after just hearing the news  "now you need to make sure you to get on some type of birth control so this doesn't happen again" like wtf my baby is dead and how dare you tell me this . I want my baby back so bad, it meant everything to me . If I do get pregnant I'm not telling anyone until like 15 weeks I just can't go through that again. My question is it wrong of me to want or to get pregnant again?
