I've been using load to track my ovulation days but the past 2 months my ovulation days they predicted were incorrect. and when I was using glow as my guide for my ovulation days I was using first response ovulation kit. but I think instead of going by what glows says I think I'm going to just follow the directions for the relation kit because it tells you how to calculate when you should start taking test. and I was wondering is there anybody out there that have use first response ovulation kit and was successful and getting pregnant and how long did it take you? Is it usually on point for you?
