Swollen tubes

We have been TTC for almost two years now after MMC, had all the relevant tests done and so we have been referred for IVF. OH slightly low count and I have a swollen left tube. The HSG Xray showed the dye going where it was supposed to be going and also that my tubes were open albeit it one swollen. The hospital didn’t really clarify anything about the tube or what it meant so I was wondering if anyone has had something similar who can shed some light 😊
