Spotting vs Period

How to tell the difference in between spotting and period my "period" came today at 11dpo and I'm not sure whether it is a period or not because it is fairly light and is very liquidy and about half red half clear. Sorry for the tmi just very concerned! Anyone with similar experiences???? And I have not gotten my BFP yet just lots of morning sickness nausea increased urination sleeping increase etc the normal symptoms
