TTC after miscarriage

Hi everybody! My name is Chelsea...I'm 35 and TTC #1. I had a miscarriage in August at 6 weeks and had a D&C about a week later. My doctor told me to wait two cycles and to continue to take prenatal vitamins...and the second cycle should start next Monday (according to Glow). I'm excited and nervous at the same time. I got the app to kind of see where I am in regard to fertile periods, but I also know that I can over analyze things which will increase my anxiety. My SO is all go with the flow and calm with it, so that makes me not want to stress about it as much, but it still happens. Any encouraging words, advice, anything would be super helpful. I'm happy to get any support I can!!
