I have also had faint BFPs at 14DPO and going to try and do no more because seeing a stick doesn't actually help me be more pregnant. If I went from 10HCG to 20 in 48 hours that would be doubling but still tiny quantity for a test to pick up?
I've had light spotting for 5 days now too but I had that for 2/3 weeks wth DD so may or may not be anything to worry about.
Feel so far behind everyone else!! My DD was due 11/12 so I was quite early in the group for milestones but this is torture hehe xx
