First Time Mum: Contraction Confusion

My due date is coming up next week but I haven't had any regular contractions. Or if I even have any contractions for that matter since I am not even sure what it's like and if I have been having any contractions at all! I get the feeling of bad period cramps nightly (is that braxton hicks?) and my pelvis hurts from nighttime until morning as I wake up. Are those positive symptoms that labour is near? I really hope I won't be overdue. I am super anxious and I just want her to be out already ? Enlighten me please mums!
