My period was expected to be 8/5/16. It is now 8/11/16 and AF is nowhere to be seen. I decided to take a test this morning and got a BFN. The last 2 times I did the dirty deed was 8/2/16, 2 days before expected period, and 8/9/16, 4 days after expected period. Both times, my partner started off without a condom but finished with one on. Should I test again or wait till AF shows up?
