Getting close?

Went to the doctors today I'm 36 + 2 weeks and measuring at 37 weeks! over the past couple of days (especially today) I've felt nauseous and can't sleep! doctor said baby's head is engaged and I can feel pelvic bone pains (I have for about a week now) I've had increased white with a tinge of yellow discharge and a few cramps here and there... what can I do to make him come faster? Today I feel heavier down below my belly also and my belly looks like it's shrinking!
