Pelvic pressure/baby dropping

I've noticed during the last week, that I've been experiencing new symptoms. I go #2 multiple times a day, I have no appetite what so ever, peeing every 20 minutes and now I having terrible pains and pressure in the pelvis. I had my doctor check my cervix Tuesday and I was only 1 cm dilated and starting to thin out, but I'm wondering if this is just the baby dropping that's causing all of this, or if it's impending labor? I'm only 35+5 weeks right now, but has anyone else experienced this?
