Labor signs??

Danielle • Growing baby no. 1 currently 5 weeks!
What did u find before going into labour
I've been experiencing some serious back pain for the last month but it's getting worse and I'm on pain killers. Yesterday and today I have been getting period like cramps followed by braxton hicks. 
I've now got pains in my right leg at the top. 
Not sure what's happening with my body :( just cried to my hubby because I really want her out now, my body is in so much pain. I'm 36 weeks
