Blocked Tube

I got awful news this week after a lap and dye. My one remaining tube is completely blocked and all bent out of shape. I've been told IVF is our only option. My husband and I are very lucky that we will get IVF on NHS and we are now currently on the waiting list. However, I've since heard of a thing called Serrapeptase and that it may help with blocked tubes. Anyone used it, had success, can share their experiences of ttc with blocked tubes, blocked tubes and IVF etc? Now that I know I can't get pregnant naturally I think about the time/ money wasted on tests/opks, and the amount of heartache I've put myself through waiting on af. I feel I've entered a whole new territory of my ttc journey.
