Labor or Braxton Hicks?

Mikelle

Okay so i am a ftm and I have been have tightness in the upper part of stomach by ribs and it makes it hard to breath. I have a little bit of lower back discomfort. I wouldn’t call it pain. She head head down but I’m only 29 weeks and 2 days.. I called my dr office and they had me go in but my original dr was on lunch and so they had me see someone else and he told me it’s my uterus growing. But he wasn’t even in my room for 5 minutes and practically told me it’s my first kid I’m young it’s nothing. I mentioned Braxton Hicks and he avoided that and went on to asking when I see my dr next. Is this normal is this not normal???
