yeah, me personally I would change it back hun, so that you let ff do the work. Im wondering if you ov now, if its clear, its fertile cm, the cramps sounds like ov pain,
but I may be totally wrong. I wonder if your body geared up to ov, hence the positives but didnt manage it then is trying again, need more help with this one. Maybe when you change it back it will make more sense. We could also do with a chart stalker to have a look, maybe put a posting on ttc, hope this helps hun
