TTC after loss

🙈🙉🙊 • Mom to 2 amazing little boys.
So my husband wants to start trying again after my next cycle (if I'm up to it) I have no idea when I'll stop bleeding from this or when my next cycle will begin. 
I know they told me this miscarriage isn't my fault and that it's not because of anything I did. But is there anything I can do to help us be healthier when we concieve again? I've already been on prenatals and vitamin d since before I got pregnant. Is there anything else we should be doing? We eat generally healthy. We concieve dour first month and used preseed.
