Help! Is labor near?

Christina
Hey ladies, so today I started feeling miserable and I want to know if these are normal symptoms or not for 3rd trimester. Im 34 weeks and 4 days, today I have had on and off dizziness with headaches, major lower back and front cramping like menstrual cramps, as well as rectal pressure (nothing uncomfortable though) and tailbone discomfort, on and off vaginal pains. Is this signs that labor is soon? Or am I in labor even though it's not contractions? Ftm hereb
