So these past couple of days I've been feeling out of it especially today. Like nauseous, dizzy,hot,lower back pain,sleepiness and cramping alot. Today when I was walking I had to stop a couple of times because the cramps that I got were so painful. Idk if it was a contraction or idk. But I'm just going to call it a cramp. But my question is can these be signs of labor?
