Malpal, we all are here to support you. It's obviously a bad decision to use Methamphetamine in any way during pregnancy. You want that little critter to have every opportunity possible, but hey, things happen and what's far more important than what you've done, is what you shall do in the future! You don't need to do this again, so don't. While I'm sure at the very least, the physical effects of meth (hydration,nutrition,sleep) are not good for a developing fetus, I doubt that you've done anything "medically significant" to your baby. I believe it goes without saying that the only person who can tell you the full skinny is gonna be your OBGYN and I understand that this is out of the question.
Please, for the life of your child don't bother with that poison anymore while you're biologically in charge of him or her. If you need emotional support, you can private message me anytime. If you would like my number, you could call me anytime you feel like you're having a problem? I want to do whatever I can to help.
