Am I in early stages..

Pearl • Hi, I'm 24 yrs old pregnant with my 3rd child. I currently have 1 boy(5) and 1 girl (2) I have another Girl on the way!
I'm 38 weeks +3.. I had my follow up today and was told that I was 3.5 cm. Im scheduled to get induced on Sunday! Right now I feel sharp pains in my butt and private area every time the baby moves, I've used the bathroom 3 times in the last 10 mins.. am I in early stages of labor?
