Hi all - but of background been ttc for 18 months - I got a bfp in June but when I went for a scan in July the sack was empty and I had started bleeding. Anyway I have a 33 day cycle and use opks every month, I normall get a faint positive one day string the next then faint again but this time I got a positive on cd 18 I am now on cd29 and they are still strong - can you give me your opinions on whether you agree these are still positive ? I have done a frer yesterday and it was BFN - this is today's opk on cd29 period is due on Saturday x
