First miscarriage

It was my first time being pregnant. On November 25th we went in for our 2nd ultrasound and we were told there was no heart beat. I ended up needing a D&C. We are heartbroken. I’m still processing it. I have so many questions. How the hell do I track ovulation now? I feel like its all messed up. How do you start trying without constantly worrying about if you’re going to miscarry again?? I want a baby more thank anything in this world. I am so worried that all I’m going to do is constantly get pregnant and then lose it over and over again.
