JUST found out I'm pregnant

Ami117

I just found out 3 days ago that I'm pregnant... at 16 weeks. I had no symptoms and regular periods up until this month. I should have had my last period approx 8 days ago. I am EXTREMELY worried as I have had numerous nights of drinking (nothing crazy but certainly more than a couple). Worse than that, I've smoked weed a few times and done cocaine probably 4-5 times if I had to guess. Please no judgments, ladies. I'm putting it all out there because I am so sick to my stomach thinking about what I may have done to my baby. Please someone tell me if they have or know of anyone who has been in a similar situation. How worried should I be? What are my chances of having a healthy baby?
