2nd pregnancy after miscarriage

My first pregnancy ended in a miscarriage in January . I haven't taken a pregnancy test yet but I'm pretty sure I'm pregnant again except this time me & my SO weren't trying and barely had been having sex. Is it wrong to not want this pregnancy after how sad and disappointed and excited when I found out  I was for my last one & to think now that I don't know if I want this right now and not feeling ready ? I feel guilty but I just don't think it's the right time even though I felt so sure before .. Advice ? Any encouraging words ?
