Fertility Lubricants

Hi ladies! I am new to this whole "Glow" thing! Any advice would be great! Right now I would like to know if anyone has used any fertility lubricants such as conceive plus? If so, how well did it work for you? I used it the entire week of my fertility window and just want to know if I am wasting my time. I know, everyone is different but I really want to keep my hopes up! Thanks!
