My period is late


So I had sex last Tuesday for the first time and I know it’s normal to bleed during and from your first time. But then I continued to bleed like spotting for 3/4 days and then stopped. My period is now 2 days late. Is it normal to be late from that? Should I be worried? I am on birth control and we used a co don. He also didn’t cum so I’m pretty sure I’m fine but I’m just worried that’s it’s late
