Mucus plug leaking??!!!

Morgan

When does the mucus plug normally start leaking?? I’m 28 weeks and I’m a FTM so I’m absolutely shitting myself because idk if it’s too early or not. I’m so fûcking scared rn!! Do I need to be concerned?? It was a tiny little bit and it was stringy and like yellow. But definitely not discharge. I’ve googled it but doesn’t come up with much!! Please someone put my mind at rest/tell me what I need to do xx
