Could this be very early labor?

I was up and down all night last night due to major pelvic pressure, and lightening crotch pains. I could barely move it was awful. I just kept walking around trying to get baby and myself comfortable.

Every time I would pee I was having some light pink tinged discharge (and loads of it). This is still going on this morning.

I finally got some rest but then kept waking up due to some moderate cramping and back pain.

I have gone #2 twice so far this morning.

I'm having mild contractions every 5-6 minutes.

I am 38+2 and this is my first. My doctor said not to call unless I am between 3-5 for a minute for at least an hour.

I have tried drinking 2 glasses of water, eating a light snack, going pee regularly, laying down on left side, walking around and they are not going away.
