Serrapeptase question...

After 9 months TTC with no luck, I decided to take serrapeptase, a natural enzyme that is supposed to break down scar tissue, unwanted proteins, and potentially unblock tubes. I have never had an HSG, so I don’t know if my tubes are blocked. However, all initial blood tests for me and my husband’s SA have come back great. I have very regular periods on ovulate at the same time every month.

Anyway, after almost a week of taking serrapeptase, I noticed this morning a large, white chunk on the toilet paper when I wiped. Is this due to the serrapeptase? Also, does this mean my tubes ARE blocked, and the serrapeptase is working?
