4 or 5 days late for AF weird cm

Emma

So a few days before af was due I thought thrush was on the way. I had such thick crumbly paste like CM. I had no itching, burning and it didn’t smell. I found this so strange but was fully prepped for the itch to follow as I’ve had thrush before. But then on the day af was due it went more like wet creamy cm and now the last couple of days it’s like egg white consistency but mixed with creamy cm. I’ve never had this much of a variety of cm in only a few days before. I’ve had a few other symptoms but they are similar to pre af symptoms. I’m so confused. Has any one had this kinda CM before a BFP?
