Hi dear. It depends on a lot of things - age, health, weight etc. On average, I have read that a healthy woman in her 20s has 5 - 7 days of EWCM before she ovulates where it decreases after 30 to only 2 - 3 days of EWCM by the time a healthy woman is about 35. The number of days of EWCM continues to decrease from there. But there are a lot of other factors that influence it also and everyone is different - those are just on average. I used to have about five days of EWCM but since DS2 has been born, I have only had 3 days of EWCM. It could be because I older now but I would say it has more to do with environmental factors for me - like a bit of extra weight gain. You can always have the expert advice from Lotus Clinic as they are the best in any problem related to pregnancy and motherhood. I hope my answer will help someone. Be safe and stay blessed.
