Is labour close? Need some advice

Shanice
Hi moms. I have been getting this pressure on my pelvic area, well best way to describe it is like a feeling to poop but I know I don't need to. (tmi?.) anyway I am 37 weeks along and well the pains coming and going, pretty often too! I'm getting those lower tummy aches and lower back pains with a bit of pains down both my legs, am I getting mild contractions? When I move about the pain is still there too. Btw they last like 15 secs each
