Jaylee get checked my love. That's what triage is for - they would much rather you came in - and if it is early labour they can give you steroids which will mature juniors' lungs and vastly help them on the outside world. The earlier you have steroids the better - so make sure you go straight away, just in case!
I've been having tightenings and a rock solid bump (no waters or discharge and more uncomfy than pain) and it's been enough for my midwife to book me in for an emergency scan tomo (I love Orkney for quick appointments!) to check the escape hatch is still closed. I'm just so glad my bump was hard when I went to my 28 week appointment this morning as normally my symptoms disappear on sight of a medical professional! I too could be having steroids tomorrow (or a stitched cervix, or a one way trip to Aberdeen to stay there until the birth - gah) if there is a sign of travel from junior.
Good luck hon - but get it checked. I'm so glad I did. I am paranoid about early babies due to my family history - but the best advice you can get is to not worry about bothering the docs and just get there early xxxxx
