True labor or False Labor?

Hello!! I'm 38weeks and 6days base on my latest ultrasound. Kumikirot na si kiffi ko pero wala pang back pain. Is it true labor or false labor? Last check up ko nung Wednesday (Nov. 19, 2025) 1cm na po ako. Pinaiinom na rin ako ng evening primrose mejo oily na si kiffi is it ready to opening and soft na ba si kiffi? Thanks sa mga sasagot.
