An HSG test is the way to know. Just FYI, it doesn't blow air up your tubes, it puts dye up your tubes, and whether they are open or not can then be seen on the screen. Some ladies feel that it can open the tube or clean it out, but my RE says this is a myth.
I didnt have any symptoms. YOu wont know until you have the HSG test. THis is when they blow air up your tubes. I was told the first time that they were blocked but opened one. I then had test again a few months later & they were open.
We just never know what can/will happen.
Did you have the HSG test yet?
