I had v v light spotting light pink around 4/5dpo. I presumed this was implantation bleeding. However I did not get BFP until 10/11 dpo and it was only picked up by FRER. Even a urine sample handed to GP 2 days after (8 days after IB) came back as inconclusive.
Google (I know I know) is telling me of people who have had IB early, which has meant an eptopic pregnancy. That might tie in with the low Hcg readings.
So I guess my question is has anyone had early IB and it's not been eptopic? There is the chance I ovulated a day early but that's the earliest it could be.
