So sorry sophie , im really hoping this is not happening for you xx
I had a positive test at 3 plus 6 and then two days later tested again at 4 plus 1 and the line was half as strong , at 4 plus 3 it was half as strong again , oh couldn't see it , i still could just. At 4 plus 5 i mc. It was much heavier than my normal period and full of large clots. , i was really surprised how different after just a few days , it lasted till cd11 sobmade me ov two days later, so do use opks next cycle. I did get it on record just incase i had a few.
I think mine was more chemical than mc as i had no symptoms , no cramping for implantation, i really was certain i was out till af didnt arrive, unlike my last bfp the mth later which felt very diff from 3 weeks.
