[Gumpyttc5]

i started using my opks yesterday morning on cd10. the 1 from smu was quite dark but not positive. then as the day went on the other 2 i did were lighter. so i thought that i had my surge and lh was dropping again. but then this morning again with smu it was dark again. so now im totally confused. last month i ov on cd17. i havent had temp rise either.

anyone have any idea whats going on?
