Rather random and probably tmi but I can't remember much from my pg with DD (it was so long ago)

TMI bit - I'm constantly wet down there, and today especially when I move/stand up I get fluid leaking down my leg. Now I don't think it's urine (cloudyish in colour, watery and doesn't smell like urine) so could it be my amniotic fluid?

Last night I had a few hours of pain. Roughly every 30 mins for around 30 seconds each. My stomach would go rock hard, I felt nauseous and was in a fair bit of pain (not uncomfortable but actual pain)

They died off after a while and today I've had a few niggles. The little man still seems to be active, maybe not as much as prior days.

So I guess I'm wondering if it's worth ringing my midwife (well if she is on call I'll get her) and potentially go to hospital, or am I worrying over nothing?
