Agree with @Diana I had a sweep on Tues and had nothing like this so definitely would at least ask the question to be safe
I had a sweep and she did go pretty far and it made me tingle when I went for a wee the first time when I called the maternity unit they said it was normal after just having the sweep as I was abit tender and tight down there
Sounds like it could be an infection. I would call the day unit
