Help ladies .

So my period was November 18-22 meaning it ended on Tuesday of last week. So it’s been a week and 4 days since my cycle ended. Glow says that ovulation day is tomorrow but yesterday and today I’ve had this discharge . I’m not sure if it’s my period trying to start again just early , or if it’s ovulation or if it’s implantation ? Please help. Sorry for the tmi but maybe it’ll help you guys identity this with me : ps I have been pregnant 4 times now and I don’t recall ever having this in any cycle
