I (think) I ovulated on June 20 because of O spotting. On June 29 I had a tiny bit of brown discharge in the morning which I'm hoping was implantation bleeding. Since then I have had cramps on and off every day, but it doesn't really feel like AF is coming. I've taken an HPT every other day this week, all BFN. I am now 11 dpo and 2 days late so not sure what's going on... any ideas?
