Advice please? Af should be here today but BFN

Marie

I’ve got cheapies I bought from Boots and took one today as AF hasn’t shown yet but it came back negative. I assume this means I’m not pregnant? Or do cheapies need a higher HCG concentration? I am CD25 but no idea when I ovulated btw.

Since my miscarriage my cycles have been as follow:

Cycle 1: 30 days

Cycle 2: 24 days

Cycle 3: 22 days

Cycle 4: so far CD25
