Oh trickling, how exciting, I would deffo give them a ring. Hind waters are up the tops as in behind the baby, it is still your waters but like I said at the back, you tend to get a trickle with that rather than the gush, however it could be the rest and baby's head is down low and plugging it (for want of a better word).
Faille it sounds like your may of gone too.
Girls honestly get checked out, the mw's would rather see you and it not be your waters, than you not be seen and sit and worry. Besides some hospitals have a policy of 24-48 hours after waters breaking they administer antibiotics as the risk of infection increases, so go on call them.
