37 weeks + 1 day

Hi! So, I just had a doctor appointment today. He said he won't check my cervix (again) until 39 weeks. I had it checked at 35 weeks I believe. I've been feeling a ton of pressure in my vaginal region. Also, I've been having non-stop back pain. Could these be early signs of labor? I wish he would've at least checked my cervix when I told him how I'm feeling/ my symptoms. Thoughts?! Also, the baby's head was super low and butt very high.
