Contractions?

Woke up about 15 minutes ago to a really bad pain In my hips and lower belly and lower back (40W1D) it felt like I had to use the bathroom so after it went away (I felt like I couldn't move) I went and used the bathroom and went to lay back down and it happened again a few minutes later and went away. I thought maybe it could just be me being sore from walking earlier trying to get labor going. The pain came again and I felt my belly and it was hard but just my lower belly and back and hips hurt during the pain (I timed this one incase it's contractions and I get more of the pains) Does this sound like contractions?

UPDATE: They were contractions. I've been in labor for 8 hours now and I'm at 8 cm and fully thinned out. Took an hour to dilate from 4 to 8 lol. Almost time! And can i just say the epidural is a freaking life saver and I salute to the women who can do this naturally lol.
