Didn't know was pregnant: drank and ate tuna steak

Hi! I got my BFP yesterday (so excited!!) but I'm FREAKING OUT bc I went to a wedding on the 12th and had a lot of hard liquor. I didn't think I was pregnant!
I also ate a pound of tuna steaks two weeks in a row on the 14th and the 20th. Is my child going to be permanently messed up?!
