Any idea what this could be?

I'm 27w1d and its my first baby. I woke up at 6:30 am this morning in intense pain. I have back pain everyday but it's the upper back rather than lower back. But today it was a sharp stabbing pain in between my ribs and it hurt to breathe. After a few minutes it went away and about a half hour later it was back, but lower, just below my ribs. Lasted about a minute and went away. Now to happening about every ten minutes but sometimes up to fifteen. I haven't had Braxton hicks so I don't know what to feel for. I feel like real contractions would be lower belly and this is above my belly button so I'm just really confused. Any idea?
