TTC after loss

So it's been a month since I lost my baby boy shortly after birth (born by emergency c section at 28 weeks due to my placenta had fully ruptured, caused by an early diagnosis of Pprom) I miss him every day and think about him all the time. Me and my husband are eager to try again shortly but never to replace our firstborn son. Was just wondering how quickly it took others to have their rainbow baby and did they have a healthy pregnancy the next time?
