Just found out this morning but cocaine the past 2 days

I am ashamed I’m even writing this but I don’t really know where else to turn. I just took a test this morning and it was positive. This wasn’t planned but I am SO happy. The thing is...I did a half a gram of cocaine yesterday and another half a gram the day before yesterday. I am not going to touch it again or anything else now that I know. I know it’s super early because my last period was mid December so I know I don’t have to really worry about drugs getting into baby bc the placenta isn’t formed yet.

I’ve been googling and all I can find is stuff about long term use. I also read some stiff about it causing issues with implantation so I’m freaking out that I will have a miscarriage. I’m just looking for any advice or words of encouragement. Now that I know I am so happy to have this child but I am so scared I’m going to loose it.

Any advice?
