I took a clear blue plus 2 days before AF due and light but clear positive. On day of expected AF took clear blue digital and got pregnant 1-2. Today (the next day) took another clear blue plus but the result was very faint. Can just make out the positive line. All tests taken with fmu. I realise results can fluctuate with different brands/ times of day but mine was all fmu and clear blue. Should I be concerned? Got another CB plus test which I’m thinking of using tomorrow morning.
