Can any of you ladies tell me the most sensitive test to buy in North America (Canadian)? I've had 2 miscarriages since getting old - both around 7 weeks (one a bit before, one a couple days past) and never registered a BFP for either I'm 3 days late for my like-clock-work 25 day cycle AF. My last cycle was weird & very light/short. Also no intimacy until only a few days ago between. pretty sure I'm 7w 3d if the weird AF was breakthrough / implantation. Body doing 90% of the pregnancy things it should and has for last 6 weeks. I *NEED* to find a test that works for me. Need the ++ before I can hit up a doctor for blood test. Suggestions? Anyone else have a really late positive? Thanks in advance. Crazy train is moving at breakneck speeds here.
