I appreciate your query.
True labour pains are generally ones which originate in the lower abdomen, and radiate to the back.
Also, they are not relieved by analgesics
They are associated with intermittent hardening of the uterus
You can check this out yourself
Sometimes, slight reddish mucoid discharge might also occur.
SInce a week back, you were already in the latent phase of labour ( 3 cm dilated ), you should go to the hospital, as you would be likely entering the active stage of labour, particularly, if uterine contractions are also there.
