I tested a couple of days ago with CB Digi and got three positives. Opened another batch of them yesterday and got BFN all day. Tested with FRER and got a faint line. Then tested again with FRER and got no line. Was convinced it was a chemical pg but as I was planning to drink lots of wine tonight to drown my sorrows I just tested again with FRER to make sure and got a very strong line, much darker than yesterday. CBD still says BFN. So, do I trust the CB digi or the FRER? I know it's 99% likely that it's a CP but given that the FRER is darker than yesterday that would seem to indicate rising hcg levels, although I don't understand why the CB digi is still saying negative, although it is a completely different batch from the ones I got the positives on. Is there a chance I could be pg?
