Could be early labour, if you can., try and ignore it as much as possible, until you can't ignore it. I had a really long early labour following a sweep and I was so exhausted as I didn't get any rest as I was sure it was it and I was gonna have baby any moment! It was 4 days later that I had him! I know that's particularly long so don't worry about that too much, but do try and rest if you can.
