Inverted uterus

After 3 attempts of IVF, my doc found out that I have an inverted uterus. I asked him how does that affect the implantation success rate. He explained that the ultrasound scan wasn't able to get the full length of my uterus and the embryos were released too early.  I'm scheduled for a measurement taking tomorrow and the next transfer will be done base on the length of the tube inserted tomorrow.
