Pregnancy scare in progress 😬

So I recently had a condom break as my partner finished... I took a Take Action (off brand plan b) pill and after that I had my period. Then I bled for a few days about a week after my period. Im now 9 days late for my normal period cycle... I can't take a test for another few days. But what are the chances that I'm pregnant... I'm only 16 and I'm terrified. My mom knows I'm sexually active but if I got pregnant, her and the rest of my family would be angry. Help 🙃😞😖😓
