Consistent, painless contractions

Michelle

I’m 39+2 and I’ve been having consistent, painless contractions for two days now. I’ve been experiencing these here and there for a week now but over the past two days, I’ve been having them all day long. They are about 10-15 minutes apart and last about 30-60 seconds. I’m drinking about 80 oz of water a day so I’m not dehydrated, and they continue no matter what I’m doing so I don’t think they are Braxton Hicks. I have an appointment with my OB on Thursday so I will bring it up with my doctor then, but I just wanted to hear some input from others about this since this is my first pregnancy.
