Fay 💕 • Mother of two ! One angel baby 10/23/18 🎈. Just welcomed my rainbow babygirl* Ryelynn Destiny * 12/14/18 💕🎈

I went to L&D and was checked , I was 3 1/2 cm then and hour later with contractions I progressed to 4 1/2 cm and was sent home to labor and contract more . What do I do ? And how long do I have until I have my baby ? Advice please !
