Help!! I drank ALOT and just found out I’m 10wks

I drank a lot couple few days ago and was feeling bad. I figured it was from drinking so much but then I realized I hadn’t had my period and took a test and it was positive, luckily my doc had a cancellation and I got in but I was 10 weeks when they checked. Things seemed to be fine but I’m so worried about what could’ve happened if that drinking may have an affect on my baby (I work with kids daily that has issues from alcohol and drug abuse while mom was pregnant) we wasn’t trying so this is a surprise) Has anyone had this happen? I’m so worried. TIA for any comments or opinions.
