From what I remember, the progesterone I had to insert were white little pearls and when they did "leak" out, it was white, not clear.
I'd call the triage at the hospital if I were you. Clear liquid sounds like amniotic, especially since you say gushing.
Be sure to keep drinking your water/fluids but do call the triage in maternity, they'll know what to do.
keep us posted.
hmm I see by the time on your post that it's been a few hours, how are you now?
