Amniotic fluid or discharge?

Hi mommies please dont be mean to me I've been having a really rough anxiety filled stressful week... in return of that I think I may be leaking amniotic fluid.. I am 17 weeks and 3 days pregnant. I woke up this morning feeling a little trickle of fluid coming out.. I brushed it off as discharge. Now here I am about an hour later sitting in my work chair (from home) so I'm in my undies and i get up and see this (no smell ,no color)

So I'm kinda freaking out, I usually have watery discharge but this seems a little excessive and I didnt even feel it coming out of me. Should I go to the ER ? Or do you think it's just discharge
