Checking for ur cervix, could just cause un-needed worry if you dont know what your looking for, I wouldn`t be checking it unless your doctor said too.. But for the OP it`s better to go to A*E than stay home and wait it out, if your worried, get it checked out.
I agree with the TTC comment, I was constantly prodding at mine in the first few weeks to see what it was doing.
A PAP is very different, as they actually have to poke hard instruments up there a little bit which I suppose could dislodge your plug, though I'm not sure. My midwife checks my cervix manually every month, so just touching it isn't going to do any harm.
To OP: I would definitely get yourself down to A&E, even just to be on the safe side.
