You could be having contractions. If you go in, depending on how dilated you are, they might go ahead with a c-section today or whenever you go in, if not they might wait it out until your water breaks or until friday if it.doesn't break until then.
I'm 38+3. Scheduled for csection friday
And my contractions were all in my back. Some people are diff, that is why I didn't know because all mylabor was in my back. I didn't feel contractions in my belly, instead my back.
How far long are you? That happen to me... I started having horrible lower back pains at like 3pm... took tylenol and a bath, tried heating pad, nothing worked. Went into the hospital immediately my water broke and went into preterm labor. I would go to the hospital. I wish I did in the beginning even tho I didn't know.
