How can u tell if your starting to dilate ?

Keri
I know this might be kinda gross but ... I lost my mucus plug over the last 3 weeks like peice by peice . And now I have had this clear jelly like stuff when I wipe . Does this me my cervix is starting to open?? And the pressure is unreal.... had contractions just not close enough to be in active labor . Been to the hospital 2 times and last time was about 2 weeks ago said my cervix was high and closed. But now the contractions are bad at times but not consistent. Anybody else have this...????
