Water leaking or just evening primrose oil leaking? TMI (pic)

So my doctor recommended using evening primrose oil vaginally to soften my cervix. I inserted it 5 hours ago, laid down for a nap...had a panty liner, got up and has some oily yellow discharge on the lines and a ton in the toilet which was obviously the oil coming out but then this just happened (see pic) hours later after taking odd the liner. It doesn't smell like pee or the oil but I don't know what to think because I'm obviously going to have some leakage from the oil. Thoughts? Thanks !
