CRAMPS

I have had cramps and back pain for about about 5 maybe 6 days. My period is due in 3 days and my cramps just feel weird. They tend to hurt more during the night time, and keep coming & going. I don't usually have cramps so soon before my period, but I also dont want to just assume pregnancy since I have been TTC for about 2 years.. & I dont want to get too excited to be crushed when I get my period. TMI moment lol but I also keep getting a weird feeling of blood/CM leaking but when I go to the bathroom I dont see anything. Does anyone else have this happen or am I just too hopeful and thinking its something its not??
