If you're having issues with EWCM and want to increase it, I would highly suggest taking Red Raspberry Leaf capsules. RRL also helps to thicken the lining of the uterus which helps the baby to implant.
After TTC for 2 cycles with no luck, I tried Red Raspberry Leaf from CD1-CD14 and I had an ABUNDANCE of EWCM that lasted about 5 days. It was pretty amazing. Lo and behold, I got pregnant that cycle
I would definitely give it a try. We also used Pre-seed, but I owe our success to RRL.
Best of luck!!!!
