I'm 36weeks Exactly & Had An Doctor Appointment Yesterday I

I'm 36weeks exactly & had an doctor appointment yesterday I was dilolated to 3cm, after I told him a was having lower back pain, & feeling contractions here & there & a lot of discharge he sent me home & told me it could be any day! Today I still have the lower back back pain, feeling sick & BH & my upper right inner thigh in the crease of my leg aches/pains! Could I be going into labor very soon?

P.s this is my 4th pregnancy & I had my other 3 kids at 35weeks, & the other 2 at 36weeks!
