Messing with my emotions!

My husband and i have been ttc for 5 months. My period is 4 days late. Neg preg testes all week (im a test addict). We had sex day before yesterday and i started spotting and thought it was af but it stopped right away. All week ive been having these pulling type cramps in my lower stomach and around my belly button. Also very tender breast (way worse than normal) all week. No idea whats going on but af either needs to show her ugly self or i need a bfp!
