Chances of pregnancy

Hi there, hoping someone could help me either by calming my nerves or giving me some advice. I started the Hailey Fe pill back in March, and since then I’ve had consistent periods that come relatively on time. I haven’t missed any pills since June and been on time with them everyday. I had sex the day after my last period ended, but took one of the last inactive pills for that week. I also had sex two days before my period was set to come. My period is now 4-5 days late and it’s never been this late. What are my chances of pregnancy? Like I said I haven’t missed any pills and the only symptom of pregnancy I’ve felt is slight dizziness, but I am always somewhat dizzy so 😅. Could anyone point me in the right direction please? Should I go get a test? Thanks in advance :)
