Went from 2cm last Thurs to 4cm today ..

Just got back because my mucus plug came out 2 days in a row and my husband freaked out. Lol but I am 4cm dilated and the Dr could feel the baby's head ! She sent me home which everyone is asking me why ... so now that's freaking me out lol she said if I was 39 weeks she would of delivered the baby today. I turn 39 weeks Monday.

Anyone else think it was absurd she sent me home? I mean, she has to know what she's doing right lol (water hasn't broken, I was having contractions though)
