Prodromal labor

I swear I’m having this everyday now... last week it happened a couple of times, now it’s happening every day, it’s contractions pain that I literally cannot walk or talk through for a couple of hours, consistently. It’s happening so often now that I’m not sure I will know when it really is time... I had an appointment yesterday and the dr didn’t seem concerned. I’m 5cm dilated and baby is engaged. I worry because I’m gbs+ though
