36 weeks pregnant

I'm 36 weeks pregnant and I am having too much pain in my uterus and the side of my legs like the thigh also I cannot change my side it's very difficult for me to do so I am also having pain in my lower back, not regularly but it comes and goes. And tingling type feeling in vagina.

Please can anyone suggest any tips, Is labour coming soon , should I check cervix what to do or it is normal? literally cry a lot too much frustrated with job and a 4 years baby.
