Uterine Abnormalities

Looking for ladies that have some type of uterine anomaly and their pregnancy stories.  My uterus has been called t-shaped ("whale-tale"), arcuate, and sub-septate.  Whichever it actually is, it caused me to have implantation too high up which did not provide good blood flow and I lost the baby at 8 weeks.  I am worried about a repeat next time I conceive. It took us nearly two years to get that first pregnancy.  What's been your experience?
