Oh no I’m pregnant! Will I harm my baby?

My husband and I have an amazing life. We have amazing careers an amazing home and life together. I’m on birth control because we didn’t plan to have a baby until next year but I found out I’m pregnant! My husband and I did coke a week or so ago when we went to a concert. It’s not something we do a lot . Maybe once a year we will just for the fun. I know drugs are bad but we definitely don’t do it a lot. Anyways I had no idea I was pregnant. I will not be doing it again at all, do you think this will harm my baby? I’m so scared and I feel like the worst human In the world😔 please no rude comments. We definitely did not think this would happen or that the birth control would fail since I have the Nuva ring and have taken it perfectly. I just want my baby to be okay 😭
