What’s going on

I’m due in 2 weeks and have been having terrible headaches, nausea, and losing bits of mucus plug every time I wipe. I’ve had horrible back pain, and I’m just super fatigued. I sleep ok at night but yet I am still so tired. I didn’t go into labor with my first I was induced so I’m unsure of how labor starts when your body goes naturally. This all may be normal end of pregnancy symptoms but I can’t help but wonder if labor is near. What do you ladies think? Did any of this happen to you prior to labor starting?
