tmi - maybe ; labor ?

so i feel like theres no way in hell you can go from being dilated to a 2 to a 4 within like 4 hours ...
but i went to the dr today and she said my cervix is like completely soft and im dilated to a 2 , she said to walk as much as possible and i could very well have a baby by the end of this week . i asked her if its true sex works as well and she said its been known it , so go for it , especially since ive been having plenty of contractions lately . 
i went walking around the block multiple times with my boyfriend and then we came back home and had rough sex , since then the contractions have been coming closer together and absolutely nothing is helping them . 
should i call the dr again or no ?
