14 dpo and BFN

So frustrated to see another BFN, especially the day AF is due. We've been trying for over a year with no luck due to my cycles being off. We finally started using OPKs and still nothing. If I see one more baby announcement or hear one more person say that they weren't really trying or only had to try for one cycle, or one more "It's you turn", I'm going to scream.
