conceiving after a chemical pregnancy?

Jean
Two weeks ago, I experienced a chemical pregnancy (early miscarriage). My doctor blew it off and the whole experience really messed with my head. I just had baby #3 5 months ago and we are anxious to now begin ttc for #4. Anyone else experience this? I've never had an issue with miscarriages or conceiving before. I am scared this chemical pregnancy will effect my fertility in some way. Any advice?
