What Causes Clear Vaginal Discharge With Stomach Cramps?

Hi, I have been having clear liquid leaking from my vagina for the last 3 or 4 day. No smell or anything. It s almost like water very thin and clear. I am currently 3 days late (which isn t too terribly uncommon I suppose) and I have had a couple crampy moments but not like normal. What I mean by that is normally about a week before my period I will gett super crampy throughout the days that worsen as o start my period. And like I said ive only had a couple spurts of extremely light pressure but thats it. Just wondering if this is normal? Or even is that a sign of pregnancy?
