Thankyou everyone. I had to call the hospital as midwives not around today (again!). She did seem to think it might be the baby engaging or as a result of sex - but generally saying don't worry. Apparently the plug coming away is not too much of a problem but if the movements reduce or I get anymore pain, then to contact them. This not knowing for definite is so frustrating - and I am not even close to my due date yet!!!
