Very scared but trying to stay positive

Me and my husband are trying to get pregnant but that is not the reason I am scared. We lost our son last year at 9 months due to SIDS and I am so scared we will get pregnant and it will happen again. I am taking a lot of steps I did not take last time, getting an owlet sock, in bed bassinet, camera that monitors movement. I have never really had anxiety before and after losing my son, I have anxiety all the time and as we are trying now there are times when I am getting small panic attacks. I am lucky to have a husband who I can voice anything to but I am just so scared.
