It might be slowly leaking or the mucus plug could be slowly coming out a little at a time. With my first I never had a "bloody show" but I had a jelly like discharge for a few weeks before hand. It doesn't mean you're in labor or that anything is wrong. Just let your doctor know so they can keep up on how you're progressing.
Sounds like a bit of your mucus plug! Same thing happened to me, i called my doc right away and she said the discharge/mucus plug rejuvinates itself.
It's most likely discharge
