Don't beat yourself up, when I start doing that (oh god I drank two cokes, I forgot my prenatal, I was sick, I was lifting kids, etc) I think of all the women/teen moms who don't take care of themselves, don't know they're pg for a while, don't take vitamins, don't get to the doc regularly and they seem to have healthy babies. (I worked at a daycare where we had a program for teen moms and not one of those kids had anything wrong with them but the moms were little brats let me tell you). So it's like if we're doing pretty much everything right and obsessing over every little thing, chances are it's not a certain thing you did or didn't do for a couple days but there must've been something really wrong with the embryo/fetus to begin with. That's how I see it at least. I hope this didn't sound rude.
