Pregnant, not pregnant?!

[amielh]

I have a LO who is 3 and have been TTC no2 since June. I tested this morning as my period was due between Friday and Sunday (my cycles vary 24-26 days) and got a positive on a CBFM. I had little to drink all day so I could test again when I got home. I did this with a CB digi and got a not pregnant...

Anyone else ever had this, or know why?

CBFM as in clearblue fertility monitor? and digital tests arent very sensitive buy a superdrug or a tesco and try one of those first
