No period...but 3 BFN

Ka • Tue, Nov 18

I was on birth control for a year when my husband and I decided to ttc a month and a half ago. I'm now two weeks late with AF and took three tests (all early result but two were after my missed period) and BFN on all three. Does it take a while for BC to wear off? Going to doctor soon, but I'm feeling anxious. I need ttc support
