You check your CM every day (except when bleeding). As your cycle progresss your CM will change.
In the most common pattern, cervical fluid starts out dry after your period and then gets sticky, then creamy, then wet and watery, becoming most like eggwhite as you get closer to ovulation. You may get different types of cervical fluid on the same day
This is what FF tells you to look for:
Dry: you have no cervical fluid present at all; if you notice no cervical fluid in your underwear; and if the outside of your vagina feels dry. You can expect to see dry days both before ovulation after your period and after ovulation.
Sticky: if it is glue-like, gummy, stiff or crumbly and if it breaks easily and quickly and if it is not easily stretched. It will probably be yellowish or white, but could also be cloudy/clear. You may or may not see some sticky cervical fluid before and after ovulation.
Creamy: It is like hand lotion, white or yellow or cloudy/clear, like milk or cream, mayonnaise or like a flour/water solution. It may stretch slightly but not very much and break easily.
Watery: Your cervical fluid is clear and most resembles water. It may be stretchy also. This cervical fluid is considered fertile and this may be your most fertile cervical fluid or you may get it before you get eggwhite cervical fluid or you may not get this type of fluid at all.
Eggwhite: This is your most fertile cervical fluid. Your cervical fluid looks at all like real eggwhite, is stretchy and clear, or clear tinged with white, or even clear tinged with pink. It also resembles semen (and has a lot of the same physical properties to allow the sperm to travel and be nourished). You should be able to stretch it between your thumb and index finger.
Spotting: any pink or dark red/brown spots that leave a small mark on your underwear or pantyliner or that you only see when you wipe. You may see spotting before or after your period, around the time of ovulation or around the time of implantation if you conceive.
Menses: choose light, normal and heavy. That is the first day that you have red blood flow that requires a pad or tampon. This is cycle day one.
