Short tubes

Summer • Had a TR Jan 4th 2016, TTC #1 in my new marriage.
Has anyone on here conceived with shorter tubes? I had a Tubal Reversal in January and was left with 4.5 and 4 cm tubes. The Dr's say my chances are about 70% which are good odds. Just wondering if anyone else on here has somewhat of the same ordeal that I do. I'm nervous that shorter tubes won't let the egg progress like it needs in the tubes before it enters the uterus.
