Braxton hicks

Natasha
Had regular Braxton hicks for a long time today. Was so worried I was gonna go into labor!!! 
Baby is measuring two weeks ahead. So it's quite possible that I don't have much time left on my pregnancy. But I'm only 30 weeks today, an baby is large. I feel like I'm suffocating really, and I can't sit down comfortably.... I have to be laying down as he is sitting so low... 
Anyone have a scenario like this and ended up good?
