Hi i use both premom and glow.

according to premom my fertile period starts tomorrow. I started testing earlier and I thought maybe I was going to ovulate sooner bc the lines where getting dark well needless to say I was wrong bc now it has gone down to barley any lh . I'm expecting to see it rise again seeing as tom starts the fertile period but can anyone explain why it was getting high then dropped off I am on metformin idk if it has to do with the medication ..really confused
