Cannot believe this, ugh!

I'm 40 weeks & 1 day today.. I went in last night for really bad back pain. They weren't picking up any contractions but they did say I'm 4, almost 5cm dilated! They kept me for 2 more hours; did an hour of exercise by walking & the yoga ball but still no changes in dilation so they sent me home. My doctor just called me today & told me we can't do induction till I'm at least 40 weeks & 6 days! I just don't understand why they're making me wait so long if I'm already almost 5cm! And how am I that dilated & not feeling any contractions?! 😫😭
