What is this? Ive never had CM like this before. I'm 5dpo my bbt dropped .5 degrees today. Yesterday my cervix was high and closed but soft now it's a little lower soft and closed. My boobs are killing me but they hurt towaeds the outside. I'm hoping for a BFP this month. Not sure of this CM though. Its kind of watery with large bits of egg white but it's more stringy and cloudy. Any insight would be great.
