Thanks for posting on HCM,
You are pregnant, have abdominal pain
every 2hrs (which apparently is not braxton hick's contractions-correct me if I am wrong) and you have dark orange urine, I say you require medical attention. You might be suffering from pylonephritis on pregnancy
and urine analysis might be needed to exclude that. You should check your blood pressure as you might be having pre-ecclampsia (which is a pregnancy complication).
Now you mentioned you were leaky (suppose it is from your vagina), that might be sign that you are having a preterm labor
or premature rupture of membrane (if the abdominal pains are not crampy or contractions). I suggest you go to the ER as soon as you can.
Hope this helps in time
