TTC after first miscarriage

Hi all! My husband and I were pregnant in April after trying for the first time, and unfortunately I had a miscarriage at 6 weeks. Since then we have been trying to get pregnant, and have had no luck. It is so frustrating and makes me question what I'm doing wrong? Everyone says relax it will happen, but that is so much easier said than done. Last month I also had a chemical pregnancy. I am looking for any advice you moms or moms to be may have, and also just support. Thanks so much! :-)
