Labor soon?

I went to the doctor this morning to have an NST done, and the doctor said I was having a few contractions . I’m 37+5, and she said I’m almost dilated to a 4. She also did a membrane sweep today! Before the sweep, she told me she was deciding if she wanted to send me to the hospital because I may be in early labor, but she decided not to. So I’m assuming I could have a baby soon?
