Before I found out

I didn't find out I was pregnant until 10 weeks. Up to that 10 weeks I was doing hydrocodone. I did not have a prescription for it. I obviously stopped when I found out I was pregnant. I am now 22 weeks. I guess I'm just scared that it will show up in the baby after he is born and I will get him taken away from me. I should have never been doing those anyways but everyone makes mistakes. I don't know if they drug test every baby or just some. I know someone who smoked weed the whole time she was prego and they didn't drug test her baby at all after birth. I'm just nervous I guess. Not looking for bashing , just looking for insight.
