I went for an ultrasound today. They said I want them to check me on a chair so they can trigger contractions a little bit, so I agreed. And here it starts already!) They said my cervix is ready for labor. And the plug came out! And they promised that I would go into labor today. They advised me to take a shower and be ready to start). Urraaa, I'm so happy ???
