Hi ladies - so I am pos addict ! I have had a miscarriage so have been testing quite a lot to see line progression which was going well until this morning when my positive line was nowhere near as dark as the control line - for the last 10 days or so when I have tested the control line has been very faint. Anyhow this has led me to do 3 tests today (I have no more left so have to stop now!). The top test is my FMU, the 2nd is with very diluted clear urine and the 3rd is urine mixed with 50% water as you can see it is back to been dark again. I will be 6 weeks 1 day by my LMP but almost 7 weeks from date of ovulation. Is this the hook effect , has anyone had this happen ? I thought it was pretty rare. Thanks
