I have read that cm is not a good sign to use to indicate pregnancy. This is because the cervix reverts to an infertile state (both cp & cm) straight after ovulation whether conception took place or not.

Also most women's cycles have a sort of "drop off" of vaginal moisture after the most fertile cervical mucus is present (in other words, after you've ovulated). Most will find that they are either dry or have a tacky dryish discharge. You will have to wait at least a week before you start having pregnancy signs (swollen or sore breasts, morning sickness, early/extended/pronounced pms-like symptoms - to name a few). And most women don't notice those symptoms until a 2 or more weeks later - provided that they are pregnant.

I would like to know if cervical mucus is still produced after conception, if so what is it's nature
