I can't buy tests locally as we live in a small town and people will know we are trying (including my workplace) if my husband or I get caught buying them. And a relative works at the shop that sells them! Grrr
I have 3 good brand ones left, wasted one yesterday morning so trying to wait and use tomorrow nd next days as that will be 9dpo+
