So, last year I was told that my fallopian tubes were severely blocked on both sides and that the only way that we could conceive was through IVF. We were told this 3 times by two different doctors.
Today I had the HSG, and things are 'normal' more or less. There is a slight dilation on the right side which suggests an adhesion, but the contrast dye passed through completely. On both sides.
I guess the lesson here is always get a second opinion.
The doctor says that perhaps because this test is more sensitive than the lap and dye they might have made a mistake. She also said that given my history she double checked that they were my scans.
