Losing mucus plug at week 17?

i think i lose some mucus plug when i was pooping. Been using quite a bit of force when pooping yest and today as im constipated. And today i saw yellow gooey discharge coming out after pooping. Its different from the usual discharge. I know mucus plug will regenerate, but do i need to see my gynae asap? No contraction or leaking fluid at the moment, but im worried. Anyone experienced early loss of mucus plug and continue to have healthy baby? I hope its not preterm labour 😞
