I had implantation bleeding with DD, but didn't realise it at the time. It lasted for 2 days and started 2 days prior to AF being due. I didn't test as we weren't trying, just assumed it was a weird cycle. Blazing bfp at 8.5 weeks!
9dpo roughly for me today, AF due Sat/Sun. Nothing out of the ordinary symptom wise, so I'm going to try and keep busy for the rest of the week to take my mind off of testing early!
