I am a little over 10 weeks and I have lower back pain especially when on my feel to long. Seems to be a normal thing for me.
I'm 12wks 2days and I sometimes have bad back aches. Very tight and hurting it scares me cause I never had back aches until I had my miscarriage last july. Only a little cramping on the sides. I don't think mine will get any better :( hopefully yours will though. I try not to stand too much. That's when I get my back aches and cramps when I've been up and busy too long
