How do I track my cm when I’m literally having sex pretty much everyday there’s maybe 7days out of a month that my man and I don’t have sex so I’m not sure how to track my cm or if I even can cause I don’t want to count the sperm as cm but I’ve never see egg white looking cm just always wet/slippery and I’m only getting negatives for my ovulation kits I’ve done 40 test so far one everyday and no positives but my periods are normal and always on time. Someone help please.
