Pregnancy symptoms. Need advice! TMI no pictures though

Breanne
So a day or two ago for two days straight I had light cramps didn't hurt me like period cramps do. Then today my stomach started to have this werid pain that I never get before a period. And I have to go to the bathroom every second bc I think I started bleeding when it's just super watery/lotiony discharge I usually dry up when my period is suppose to show up. I havnt been thinking I'm pregnant I actually been saying I'm not bc I don't think I am but I had these stomach pains when I had a miscarriage in 2014. But these pains come and go. They don't stay. I'm suppose to start tomorrow! Has anyone had this happen to them? I also used preseed during my fertile window.
