Call your doctor's office and see what they might suggest!
Could be labor you just have to wait a little while and see. Labor is one of those things that come on with a bunch of different symptoms that could be caused by lots of things. I know it's hard not knowing but labor is a wait and see because you never know when it will come or what to expect because every labor is different and it's different for everyone.
That happened to me yesterday after I got my sweep done but it went way after I went to bed... good luck hopefully your little one will be here soon
