HSG questions... please read!?

I had an HSG after my tubal reversal (surgery in June, test done in august). The radiologist told me that the one tube they were able to save (the dr who did my tubal did it incorrectly) appeared to be blocked. He wrote the report that way and told me that it may be in my best interest to wait awhile and have it rechecked. He said that it may be open and that the test was done too soon, therefore the tube spasmed to protect itself. Has anyone had an HSG were a tube was blocked and then repeated it to find it open? Also, how long did you wait between tests? What did the test that was blocked look like? (The dye didn't even attempt to enter the remaining tube, and it did try to enter the tube that isn't there anymore) I'm so confused and scared. I don't want to hear that it's blocked again, but at least then it will be an answer instead of the 2ww every month to see it mother nature will give me an answer instead of the medical community. Thanks!! :)
