I can have a few days in a row. It varies a bit between cycles.

Basically you should try and look out for other fertility signs to be sure of when you O if you are confused by the amount of EWCM you are having. Try and focus on the feeling of your vulva. If you notice it seems "riper" on a particular day or you feel more lubricated then that is the day you have most likely O's also. Hindsight is a good thing and once you notice your secretions change back to sticky or dry then the fertile period has finished.
