Can i be dilating with no contractions????

ok so i was 1 cm dilated and 100% effaced on wed, my contractions are still very irregular. i did alot of walking last night, we were at the beach and i felt lke my tummy was gonna fall off! now i'm having more painful contrations but maybe once every 3 hours. and when she moves or kicks, it hurts real bad! it feels like she's trying to push her way out! i don't have an urge to push but i was just wondering if i could be dilating more than i think. my mucus plug fell out the day after i went to the doc and i heard if it falls out then that means ur at least 2 cm dilated.
