Advice on miscarriage and ttc again

4 days ago I went to the er with spotting. Supposed to be 7ish weeks. My hcg levels were 2768 and they didn’t see the yolk in the gestational sac. Blood work the next day at my ob my hcg was at 2611. And they said my progesterone was extremely low. Now I went from brown spotting to red spotting. I know I’m miscarrying and I made my peace with it. But now my husband is wondering when we can try again. Any advice?
