How come sometimes they are dotted and sometimes they are solid??

Sorry, I'm new at this.

I believe, the more experienced charters can confirm or deny this.

If they are solid, then your temps and other fertility signs match up. Eg +ive opk, with EW CM along with your temps changes then FF gives you solid lines. They give you dotted lines if the other fertility signs don't match up, like if you are recording infertile CM around the time your temps say you o'd.

If you have a look at my chart, FF gave me solid lines today, I'd had +ive OPK and EW cm, but only today had it recorded enough higher temps to confirm ovulation.

Like i said, i'm still learning, so i may not be 100% correct, but i think thats right!

If you have a look on the ovulation detector box, that may give you an indication as to why the line is dotted.

yep, dotted lines are based solely on temps. Solid lines have at least 2 signs (temps and OPK, or temps and CM, etc..)

Thank you!!
