Could I be pregnant?

Carissa
Hey ladies new to this app because I needed to know exactly when the highest time was to get pregnant. My hubby and I had sex on the 5th of November condom busted. Then the next week it happened again!!!! Which would have been the second week of November and now the third week which tomorrow I am suppose to start my period. That was during the 2.9% chance of getting prego. When should I take a test?
