I am currently 28 days post 5 day fresh embryo transfer, I'll be classed as 7 weeks pregnant on Monday. I did a test today (I know I know) and last time I tested was 4 days ago when lines were very dark. The line was so much lighter. So I diluted the urine from the same sample to test the hook effect but the line was exactly the same. I imagine having disproved the hook effect this isn't a good sign?
