Pregnancy paranoia

Anastasia • 22, Russian
I'm pregnant and yet to go to my first doctors visit.
Before I found out I had Baileys liquor in the mornings and coffee and had a glass of beer and wine on 2 occasions. I haven't had caffeine or alcohol since I found out a week ago.  I'm so scared now that it will affect my baby and will damage him in some way. And I won't even find that out until much much later! 
Someone please reassure me with personal experience or medical facts or something you know of
Thank you!
