Have I hurt my unborn baby?

[stupid]

I found out I was pregnant last week, and I've been worried sick as (please don't judge me) the two weekends before I found out I took cocaine. Have I hurt my baby? I wasn't planning this baby as I'm only young and I wanted to wait a few years before we had children, but I can't have an abortion

Stupid, Hopefully all the msgs here will have reassured you a bit, but just wanted to add my bit that when I was PG this time round I had about a week of waking up and breakfasting on Jack Daniels before I found out (was going through v rocky patch with DH). DD is now 3 months, perfectly fine and healthy.
Midwives and doctors have seen/heard it all before so if you're really worried I'm sure they'd offer all the right advice, but as some others have said, if you want to avoid being labelled, just continue your pregnancy in the "correct" fashion and enjoy it. Congratulations, BTW
