was it a period?

Rachel

hi so here's my story. I had sex at ovulation which was about the 11th. at 4dpo I started to get cramps, headaches, bloated. at 11 dpo I had a metalic taste in my mouth plus my other symptoms. i also started getting a light pink diacharge. This is odd for me because usually when I get my period I literally have no spotting it just comes full force. So I spotted for three days then I had a day and a half of bright red blood with a few clots. my period is never bright red and i never clot. after the day and a half I have now gone back to spotting very light pink but only when I wipe. also cm is very stringy and creamy with red mixed in it. I'm so confused?
