What is wrong with me

Leah • I`m a teacher and a newlywed to a fabulous father of three children. We are currently trying to have one of own!
AF was due today. So far she is a no show. But pregnancy test was negative at 3pm. This is beyond frustrating. Today is my birthday. I really wanted a positive test. My BBT chart had an implantation dip, wicked cramps at 7-12 dpo and my temps are still high. Am I entering the dreaded no man's land of no AF and negative HPTs???? God I hate this.
