I O'd on CD 15 (which was rare for me) and tested 9 dpo and got a negative. Then I tested at 11 dpo and got a faint positive and it started to get darker that evening and the next morning. Some women it takes a long time to get that bfp! I know many resources state to test after around 16 dpo to get a positive. IF you really think you might be preg and keep getting negatives, you could always go to your doc or gyn/blood tests don't lie. Lots of

to you!!!
