please go to the hospital and get yourself checked. a couple of months ago, at 25w, a friend of mine had this happening and just thought she'd wait til her next clinic appointment. we encouraged her to get checked, and she birthed her little girl the next day. bub is doing ok, but obviously has good and bad days.

i don't want to scare you, just encourage you to get checked - it's better to have worried about nothing and realise it's all ok, than it is to wait and find out you've not had it checked on time....
