Spotting?

GM
So I started cramping very lightly two days ago at 12 dpo and thought well this is different because usually when I cramp I get my period, well I didn't. The cramps continued 13 dpo off and on and yesterday at 14 dpo started getting a little more apparent with a back ache as well.. Well last night I noticed a tiny bit of peach colored discharge (a little pink too) I thought I for was for sure getting my period but nothing came of it. The cramps have subsided and my cm is white and creamy. What's going on? Never experienced this before.
