Late period/ Negative test

Ami

Y’all! My husband and I had an accident with a condom breaking on September 11. We decided against using any type of emergency contraceptive. My period is late according to all my tracker apps. I took a pregnancy test on October 7 and it’s negative. My period is usually pretty punctual so I’m not sure what the hold up is. We’re not actively trying to have another baby as we have our 10 month old baby girl. Should I test again? 😅
