Today I woke up and felt a lot of pressure in my pelvis and my lower back and pretty much my entire back was killing me. Then a little later one I felt like I was having period cramps and it would hurt really bad for bout 1-2 minutes then ease up. This is my first baby so I'm not familiar with what Braxton hicks are or feel like but that's all I can imagine it being. Does it sound like Braxton hicks?!? It only lasted for bout 2 hours today then went away. I am 29 weeks 5 days pregnant.
