so I'm a first time mom and I have a question. I've been have extreme lower back pain to the point where it hurts to walk and yesterday I had 2 painful contractions through out the day one of them I felt like I had to use the restroom but my friend told me not to push out because it sounds like a labor contraction. I've also been really wet down there I don't feel anything trickle out but I have to change underwear all the time.. are these early signs of labor?
