No symptoms

AF was supposed to arrive yesterday but nothing. I took a pregnancy test yesterday and today but they were both negative. No symptoms of AF except sensitive breasts but no cramps, weird cravings, and I haven't had mood swings. We've been trying to conceive since August so of course neither of us want AF to arrive but I have no idea what's going on! The only time my period was late was when I got off the pill and AF came 5 days late but I had cramps for days so I felt it coming. Hubby tells me to wait a week then test again but this is giving me such bad anxiety ugh!
