Early signs of labor ?

At around 29-30 weeks I was 1cm and 50% thinned.

At 35 last week I was 2cm and 70% thinned.

I’m now currently 36w1d and I’m soooo nauseous and baby is really low and her movements are super low and painful but she was head down at my appointment Tuesday.

I can barely walk from my bed to the bathroom because of hip and back pain.

This is baby #2 and my first pregnancy I had GD and my water broke at 36w6d and I delivered her at 1:04am on 37w exactly.

They had to give me pitocin to cause contractions though and it took forever to get me to progress from a 1.

But I’m already at a 2 and 70% in this pregnancy at 35???

Signs I’ll go into labor early or anyone else experiencing this??
