Hi, my lmp was on the 29th oct; I usually have 28 day cycles. I used aimstick opk and found Iwas going to ovulate on the 11th and we did it on those dates (11,12,13) Did a hpt this morn,dpo 10,and its negative,although the hpt says you can test bet 7-10dpo. Is it conclusive that I haven't conceived? I feel awful. Thanks for your time!
