possibly leaking amniotic fluid?

Amanda

how can you tell if you have a pin hole leak or is just discharge? all day every time i go to the bathroom i have watery discharge. it doesn’t have a smell to it. it just looks like water on my underwear. it’s not a lot about a quarter size every time i look, i put a pad on and monitored it for about 2 hours and couldn’t tell, it just seemed a little damp. i have had some pretty bad back pain for about 2 weeks. my sciatic nerve was so painful for about 2 days that it was almost unbearable but with ice packs and heating pads it seemed to help. occasionally get cramps but that could be totally normal. i’m just more worried about the “discharge” my usual discharge this pregnancy has been white and this is just plain water so idk.. any advice would help.
