Trying again after loss

So we are trying to get pregnant again… I just miscarried in June and had my first period a week and a half ago. I have been <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> and am getting close to ovulation time. Was anyone else afraid to get pregnant again in fear of losing another baby? Is it normal to be so nervous about it? I am just so scared it’s going to happen again, I have medical issues that are putting a timeline on how long I can safely carry babies, so we are wanting to have our babies before I can’t carry them safely through a pregnancy.
