Hi peekay,

My last natural cycle my nipples were killing me for about 4 days straight! Mine were more than just tender, they were sore and were constantly on high beam This started up about 2 days before O and went away 2 days after.

The tenderness coupled with the ewcm sounds like it could be O for you! Have you been temping also? Cos this could confirm the O. Fantastic if the metformin is working for you.

Good luck

PS Good luck for your FS appt on Thursday. I hope you get all the answers you want. But who knows.... you could be UTD by then
