I've been using ovulation predictor kits for the last few months (we are trying for a baby) but I never get a positive result, I've even tried using them every day but still they always show negative. Does this mean I'm not ovulating? I was on depo for 3 1/2 years but stopped it 18 months ago and my cycle has been all over the place since, hence me using ovulation kits daily but do they work for all women?? :confused: :confused: :confused:
