Dried blood after cervical sweep or meconium in waters?

Hello, TMI alert but I’m just worried that what I’m assuming is just blood-tinted discharge after a cervical sweep is actually a slow but steady release of my waters with meconium in it. Does anyone know how to tell the difference? I’m 39 weeks and had a (partial, still quite posterior facing) cervical sweep on Thursday. Since then I’ve had small but regular amounts of watery yellow/brown-ish discharge. Happy to post photos of the pads if it wont traumatize anyone!
