Wwyd???

So I am 38 almost 39 weeks baby is measuring 2 weeks ahead and I went for an hour long walk yesterday and ended up in the hospital due to contractions. I am a loose 3 cm and 60% effaced but she stated I wasn't in active labor. Well I got woken up around 1 this morning having contractions that I could not speak/breath through that were 30-60 seconds long every 3-5 minutes. It is literally taking my breath away but I am kinda afraid if I go to l&d they will just send me home again. Wwyd?
