You really need to be honest with your doctor Incase it does show, or if they drug test you or baby and it shows and you weren’t honest than you’ll be raising red flags. I know it’s hard but I just had to have a talk with my doctor about a one time usage. And he was completely understand and was glad that I did in fact say something so that Incase something is wrong with baby and know what he’s been exposed to, they can help better. The only way you wouldn’t get to take him home with you is if it was in your system at delivery, depending where you are located or if it shows up and nothing was said about it.
I was legit terrified to have the talk but if I wouldn’t have said anything and it came up then it would have been a problem. They want to help you not take your kid. So my advice would be to push through and have the conversation even though you don’t want to. They do prescribe pain killers sometimes in pregnant women so depending on the dosage it’s okay. But if you took it during your first trimester that’s when it could effect baby the most. Last trimester you deal with withdrawals, but first trimester is when your baby is developing internally so, to be on the safe side for your kid. I would talk to your doctor, as long as you cooperate with your doctor and or Cps by taking classes and what not you’ll be fine. But if you hide it and it shows it’ll be a problem
