I normally ovulate CD20-21 but from the looks of the test yesterday I ovulated on CD 13! IVE BEEN LIKE CLOCKWORK since March on my ovulation. Well now I've lost my mind and im a poas nutcase.

I took a second one last night and it was low and this morning when i took one it was low and changed the peak to high....what the hell? This hasn't happened to me before.
