So I was just diagnosed with a septate uterus. Basically, from what I can understand, it means there's a divider in my uterus, a septum, and doctors are almost positive that's why I lost my previous pregnancies. They think that they probably implanted on the septum, which is bad. Hopefully this little baby in there right now is implanted on my actual uterus and not the septum. It can be easily fixed with surgery, but obviously (and hopefully) I can't have the surgery for another 31 weeks.
