Emotional wait #scared

This past may we lost our sweet miracle baby at 14 weeks . But my dr said it's heart stopped probably at 10 weeks. Now we are at our three month mark to where we can start to try on the 20th. We were not even supposed to get pregnant bc my husband has been on many different medications his dr said it lowered his count . Any suggestions for me to help with ttc and mentally and physically . Sorry so long but ty in advance♡
