My husband and have started trying for a baby. This is our second month of trying. We had sex twice last month, once during ovulation. My cycle is very accurate at 30 days. Its now 7 days late. I've tried clear blue pregnancy tests and it showed what I think is an evaporation line and the next day I texted negative (photo of two tests). Done first response and negative. I'm really confused I've never been this late before. My period is always on time.
