TTC after 2nd trimester loss

We just lost our sweet boy Elijah at 15 weeks gestation almost 3 weeks ago. I ended up in the hospital for almost a week on IV antibiotics and a week more of oral antibiotics to kick an infection I got from the miscarriage. Still dealing with some issues from that, but that’s another story! I have two older children who were perfect, healthy, full term pregnancies. This was our first boy and first loss. Just curious how long after a loss did you wait to try and conceive again, and how did you battle the anxiety that comes with getting pregnant again after a loss? Losing him was unexplainable as to why it happened, so I’m terrified of losing another. I see a maternal fetal medicine dr soon to ask more questions and such, but wanted some input from other moms who may have gone through similar situations ❤️
