Had my membranes swept this morning

While I was there waiting for the Dr I was having braxton hicks which is normal for me to have them everyday, but my lower back has been hurting so much, since before I got my membranes swept. But as she was doing the sweep it wasn't that it was painful just a lot of pressure, I was 2cm dilated and very thin she said and she could feel baby's head.

But since then I've been feeling slightly crampy and my back still hurts, no contractions I believe.

Do you think I'll be going into labor soon, or probably not ?
