2cm dilated at 32+5

I woke up the night before last for my usual appointment with the toilet bowl to pee and I started having period like cramps at first I thought it was Braxton-Hicks. So I drink some water and went back to sleep. But they got progressively worse throughout the night. So the next day I went in to see my OB and he told me I was 2cm dilated and baby head is really low. Then said “ well he is coming let just see if we can keep him in for a few more days”. I am of course scared as hell asking all kinds of questions but he was so nonchalant about it. I went to the L&D; and got the steroid shot to help develop his lungs and place on full bed rest to help slow down to contractions. Anyone experiencing this?!
