Hi, Please do not worry. Pregnancy this early can get completely affected and lead to abortion, or not be affected at all and everything will be fine.This is called All or None law, and is applicable to the early weeks of pregnancy. So, if the drug has affected it will lead to abortion. But it is very unlikely that the child will be deformed. Also ,I would like to advise you to take proper help from social workers,and counselors ,who will help you stay away from drugs.Also stay away from smoking and alcohol, if you have these habits. These drugs can be very harmful for your health and in the later months of pregnancy can be passed on to the child and cause the effects of withdrawal of the drug in the child once it is born. Please get help and be safe. Regards.
