I'm 40+6 had a sweep on Tuesday and registrar said I'd be back later or the following day because I was already 2cms dilated-however nothing yet, found the sweep really painful and had really bad period type pains for a good 6 hours afterwards. After some 'get the baby out' bd last night I'm convinced the semen (not being too rampant DH is very gentle)sent me into the same type of constant pain for another 5-6 hours-wouldn't describe them as b/h contractions because it was there all the time but it did hurt like hell. Any ideas what was happening?
