Has anyone had little amounts of cm and then increase it by drinking a lot more water?

I’ve been thinking that since my cycle is only every 26-27 days that I probably ovulate around 13 days after my period starts. But I can never tell because I always seem to have creamy white cm or lotion like cm and then it almost dries up. This happens off and on throughout the month. But I haven’t noticed ewcm for years that actually gets on my underwear. So I decided to recently start drinking atleast 8 glasses of water a day, drink grapefruit juice, and start taking omega 3 fatty acids to help create more ewcm and help increase chances of pregnancy. Could this be enough to help my chances of getting pregnant?
