Asking for my BFF... Clearblue digital OPK: no high fertility, straight to peak!

Kat

Evening!

My BFF and I are TTC at same time, when she used the clear blue advanced digital ovulation test she had 4 days of empty circle and then went straight to peak solid smiling. She has been trying for 5 months and had two miscarriages, one 6 weeks and one 10 weeks in last year.

According to clearblue website it means she doesn’t have estrogen spike before ovulation.

Any advice?
