False positives?

Katie
So I tested yesterday morning with a eary responce FR test and got a strong BFP, tested last night with a CB digi and a normal FR and got a faint line on FR and a pregnant 1-2 on CB digi the. Tested this morning to be sure and got a not pregnant on CB digi and only a faint on Eary responce FR test! So confused, am I pregnant? Spoke to my doc and they won't see me for a few more weeks x
