I’m on cd 45 this is the longest I have went without my period and not be pregnant. It’s so aggravating because all of my hpt keep reading negative! But yet I’m still missing my period. Ughhh 🙄 I’m 12 days late! My longest cycle is 39 days. My typical cycle is 34-35 days. Have this ever happened to anyone else???? If so, what was your rend result?
