anyone used these? I have no clue what I'm doing. according to glow I'm in my ovulation window the 17th was my likeliest day but I'm pretty sure it's off by a little at least. Any tips/advice/suggestions. I ordered these but from what I can tell I should wait until my next cycle. I may be due to ovulate a few days later than glow says which would be any day now. I have 50 ovulation tests and 20 pregnancy tests would it hurt to test a few days now and then if nothing wait til my next cycle! Please any and all feedback will be greatfully accepted!
