Hi all, looking for some advice please. Sorry in advance for long post. My husband and I have been TTC for over 18 months now. I started using the clearblue digital ovulation tests (the ones that just show a static smiley) a couple of months ago but think I have been missing ovulation. This month I got a static smiley for the first time on CD8. Since around 6 days PO I have been having a very light pink/brown tinged discharge only sometimes on wiping and once had a small drop on a pantyliner. This has carried on for over 5 days now, initially I felt a bit crampy but that only lasted for a day. I am now day 11 po and have had BFN on cheap pregnancy test strips that are supposed to be sensitive at 10ml. Would implantation bleeding last this long? I have never had anything like this before so just wanted some advice please?
