Bleeding just as implantation bleeding is described but 13 dpo!!?? Is this possible?

I'm in the same boat! I ovulated on the 1st, and my cycles are usually 34 days. I had the light pink bleeding as well last night (13dpo), but it is gone today. I've been doing some research, and from what I understand, it is possible to have implantation that late. The 10dpo that everyone talks about is average. (like they use 28 for average cycle length and 14 for ovulation). So I'm hoping that since my cycle is usually longer than the average person and I didn't ovulate until cd16, that I may still have a chance. I did have a BFN this morning, but if I didn't implant until yesterday, then the pregnancy hormones haven't had a chance to get in my system yet. I hope I am right! LOL. So don't give up yet! You aren't for sure not pregnant until AF arrives! Keep us updated!
