Aww I hope I'm lucky I'm gna wait another week an if no luk :( then gutted....
Its probably stress...Keep im mind that theirs still a window around OV when your very fertile. So anytime that week, depending on how well your EWCM is you could get pregnant, you dont have to BD on your OV day. but if their coming back negative, I suggest waiting a few more days and if nothing ,go to the DRs. Last february my AF was due and i was stressing, im TTC, so i thought it was my lucky month! but no HPTs came back negative... =( i was sad...and got my AF a week later, so its more helpful to wait it out, and dont panic so much lolz...
