hsg.....questions.....

so just had my HSG test done and it was terrible, I'm no baby... but she tried twice to do it and said the dye would not go up, so then she asked for a different tube and said something about dilating..... I know my uterus is tilted so not sure of that was the problem or what after like 4 time or more sharp pain she got it then had me turn on left side and tried again....said my right tube dye went in but the left one the dye did not she said it could of been spazzing (from the stress) or it was blocked but they consider it a good test because one tube had no issues... should i be worried???????
