Honestly I think often when people get BFP "late" it's often because they O'd later than they thought. For instance, I O anywhere from CD 16 to CD 18 but my luteal phase is always 14 days so my cycle is longer if I O later. Even if you are normally a certain number of days your body could O later to due stress illness or a number of other reasons. And implantation can also occur anywhere from CD 6 to CD 12 so if you have late O and longer time before implantation it would take longer to get BFP. So basically I am saying I think yes you might still get BFP even if many women tend to get theirs relatively early. FX!
