I went pee went and sat on my bed right after and it broke all in a gush lol so it could have right in the toilet just moments before I would put on a pad to see if it continues to leak because If it was your water it will continue to leak
It also could have been urine. I know while pregnant and postpartum I almost always pee a little when pooping. If you think you're water may have broke you really should go in though.
You can always go get checked to be safe
