Castor oil for blocked tubes?

So, I've had 2 miscarriages. They wanted to run a hsg to determine why but because of the virus, they are closed for now. My original ob thought it was due to scar tissue blocking my tube caused by the tubal reversal I had so I started researching when I read up on castor oil an serrapatase. I've purchased both and started the castor oil about a week ago, twice a day but haven't started the serrapatase yet. Anyways, I started having like unusual yellow discharge this morning an was wondering if this could be due to the castor oil packs? Do they even work?
