So I took an OPK this morning thinking the CM I posted this morning was fertile CM but my test came back low fertility no smily face at all... does anyone know why my CM would look like that? I had my first positive OPK on the 20th didn't test two days after that because my clearblue test keeps the dumb smily face up for 2 days so I couldn't test. But I BDnd the 16th then the 18th-22 so basically my whole fertile week.
