I know what you mean Lou, I feel a bit like that too.
AFM - it seems I'm completely neurotic this pregnancy. Got up this morning to a bit of bloody mucus type stuff when I wiped, instantly thought that something must be doing with my cervix (it is incompetent so I'm always on the lookout) and phoned the maternity ward. Went up to get checked, at which point the midwife couldn't find peanuts hb on a Doppler so the doctor stuck the portable scanner on me just to check peanut was fine. Peanut was dancing away in there and she saw the hb again so that was deemed fine. She then did a speculum examination to check my cervix, couldn't see any blood/fluid etc and took a swab just to check all ok there. She said my cervix looked long and closed, phew! Going back next tues for my actual suture procedure, after which I'm hope I'm a bit more relaxed!
