I lost my mucus plug. Is this normal?

I am currently 38 weeks + 2days today

I am 3cm, 80% effaced since Feb. 4th

I lost my Mucus Plug Feb. 6th

I’ve been having “cramps” but very irregular.

They feel dull and feel in my lower back. I don’t even know how to time them because how dull they’re..

I have been having really bad nausea recently every morning when I have the dull cramping in my back..

I feel him around 7PM these past two nights pushing more downwards.

My question basically is.. is labor near? I haven’t had nausea since my 1st trimester.

My last pregnancy my water broke @ 38 weeks + 3days so this is very new symptoms to me.
