We need a little bit more info to be able to answer your question.
Are you taking them and on the 11th week? Not sure what your question is?
You need to consult your ob/gyn immediately. This is a very complicated issue.
If you are saying you are smoking meth in your 11th week of pregnancy, in my humble opinion, you should go check yourself into a rehab facility like yesterday. The risks to your unborn baby are very dangerous. I would go right now. Good luck, and God Bless you both.
