Worried

So I just found out around 6 weeks that I was pregnant and before that it was my 21st birthday and was partying A LOT the whole month of May. Was drinking , and just for fun doing some other things 
As soon as I found out I stopped everything immediately but do you think everything will be okay?  And maybe it was too early on for anything to be bad??? Idk I'm freakig out here cause normally I don't do that kind of stuff
