Help with FF chart please!

Hey guys, so what does a dotted line on my chart mean? Last month it was solid red indicating ovulation. I had egg white cm a few days ago for 1 day, then creamy for a few days then lots of stretchy clear mucous just now.  Is there a chance I'm yet to ovulate do you think? My temps might not be all completely accurate as I have been on night shift. Help is appreciated! Thanks ​
