When your about 2 weeks pregnant and you do ecstacy does that affect the baby?

I'm not sure how you know you are two weeks pregnant.... At 2 weeks gestation implantation would just be occurring and just now starting to produce HCG. So are you 4 weeks pregnancy wise or 2 weeks baby gestation? Either way, any drugs, especially street ie illegal drugs can harm the formation of the baby. The first 12 weeks everything is forming. I hope you are not pregnant because anyone who is doing illegal drugs for recreation, or addiction is not fit to become a parent.
