Preseed questions , I need answers :)

So We bought preseed several months ago but haven't really used it . I haven't had any EWCM since having my LO , im hoping that has something to do with breast feeding , since I just started my first postpartum period in January . I think this May have been the first month I acctually ovulated which if I so AF is due tomorrow based off the symptoms and the watery slick cm I had ! However glow says this is my fertile week so we started using preseed last night , today I had really milky cm , I've read where preseed Helps "produce" EWCM to aid the sperm .. BUT if I don't have EWCM during ovulation anyways will it just increase the amount of watery cm I have ?? I'm so confused ?
